How to Fix or Troubleshoot WordPress Plugin Conflicts

There is a reason why every plugin (WordPress and other repositories) give out so much detail. For example, customer reviews, technical specifications and extra valuable information. This information is usually provided about every listed plugin or theme. This is because the developers prefer users to review the report thoroughly. Also, they want users to make a well-informed decision on plugins to use on their sites.

It is particularly imperative for all those users who are not capable of code inspection. But, they wish to know the potential issues that every user must be aware of. So, always pay close attention to key detail when reviewing new theme or plugin in WordPress. 

Every plugin's main page offers users with ample opportunity. This is to ensure developers maintain and update their plugins alongside WordPress. Also, a user can check what others say about the plugin functionality. This is in the reviews and rating sections. Further, these reviews help in knowing issues that users are experiencing under Support.

With this last tip, you can quickly know and discover the plugin conflicts. This is before these issues have had a chance to attack your WordPress site.

But what about that one time when the issue is not publicly reported?

Well, if we assume that issues have not been publicly reported, then it is time to deal with them manually. Also, immediately. If not, you will face a frequent disruption in plugins performance. Further, an error message popping up again and again. Or, to be worse,once again the white screen of death.

Do you want to keep your WordPress site functional and to avoid the above issues? Here are the most repeatedly occurring scenarios. So, keep yourself updated with these frequently occurring issues. Also, find out what you must do about them.

Scenario 1 – When your site is up, but your installed plugin is non-functional

Is any of your installed plugins is causing a problem, not working correctly or not working at all? Even so, are you still accessing your WordPress site? Then, immediately check for an available update of the plugin. Anything about JavaScript or CSS within the plugin may have set off the problem.

In this case, follow the standard process of plugin update issuing. After that, do check your site's functionality. If the issue gets resolved, it means the plugin developer understood the conflict. And, has rectified it now.

Scenario 2 – When you update an existing plugin or install a new one, but something got broken

Have you installed a new plugin or updated an existing plugin? You can easily find the busted website's source. Besides, in this case,there is no need for any troubleshooting.

All you need to do is to deactivate the plugin which you suspect is causing a problem. After that,return to your WordPress site. Now check if everything works fine. If yes, the next step is to report the faced issue to the plugin developers so that they can fix it once and for all. While waiting your plugins' resolution, find a replacement for that particular plugin. Or, check out some resources to get a hand-picked suggestion for a replacement.


Scenario 3 – When you go with batch or automated updates, but it turns out to be a mess

Automating theme, core and plugin update in your WordPress is not wrong. But,sometimes things can get quite messed up. Nonetheless, this is a smart business move. Reason being, automation and streamlining are the significant drivers of success. But, if you like to automate your WordPress updates, fixing plugin conflict might not be easy.

Depending on what the error is about and how it shows up on the website, you might need to take two different paths. These two paths may be regarding:

  • When the theme or plugin breaks or a message (error) appears at the top
  • When you suffer from a white screen of death

Let us discuss each one of these issues in detail separately.

When your theme or plugin breaks or an error appears at the top

 Are you facing this situation, but your WordPress is running and easily accessible? Then here are some steps that you must take. Nonetheless, these steps are necessary if anything on your site breaks just like that.

  • Look for your recent backup file. If this backup got made recently and right before the plugin update then restore it and skip to step no. 5.
  •  In the case of having no recent backup saved, deactivate all the plugins. Every single of them, by going into WordPress. But, to do this, you need to go under plugins section, merely checking off every plugin in one go. You can do this by using the bulk deactivate option which will shut all them off.
  •  Now check if the WordPress issue got resolved. Also, check if your site is working correctly. If yes, then you know that your plugin is the primary issue.
  •  Meanwhile, switch your site theme to the WordPress default theme. However, do not just hunt around looking for a WordPress default theme. Instead, go to Themes> Add New and the first theme will be your default theme there. (The theme update is usually at fault when the developer includes new functionality. That starts mirroring the functionality of the plugin you are using already. So, your best bet is to rule this one out. Recheck the site and ensure that it is no more having the issue. However, if the problem is persistent, the chances are that your theme is causing the problem. In this case, you need to establish contact with the developer to discuss the issue. In the meantime, look for a replacement theme)
  • If by switching the theme, the problem got fixed, then one by one check each of your plugins.
  • You may start it by merely reactivating the first plugin if you have access to one. If your site is a specialized e-commerce, membership, hospitality website, get one. As you reactivate the first plugin, check if your site is problem-free by doing this.  
  • Now, add the particular plugin which you think is causing the problem. Did your website show an error message before? If so, then it would have also told you the real name of that problematic plugin. However, if not, you may start with the plugin that is not working.
  •  You must continue doing it with all the plugins unless you figure out the one causing the conflict. Also, ensure you deactivate the plugin that you recently vetted. This is prior activating the next plugin. As a result, you will cut down the various variables. These are variables you consider to figure out where the current conflict exists. 
  •  Once you figure out the plugin conflict, report the problem to the developer. But, after deactivating the plugin. You can say it to the developer in the repository. Or, with the support team in the case of using a premium plugin.
  •  Now, it is your choice if you like to roll back the plugin to its previous version. Use a replacement plugin, or to go without this particular feature completely. However, it is not recommended to roll back to the last version of the plugin. Because, you might continue facing the issue. Also, you must always use only the recent release of plugins, core, and themes on your site.
When you suffer from a white screen of death

Every WordPress user knows what a scary prospect this white screen of death is. 

But, only if the first behind this scary prospect is a recent update batch. Then, fortunately, the solution is an easy and instant one to install.

  • When a user suffers from the white screen of death, they cannot access the WordPress site. This indicates that you cannot access your plugins. In this situation, access your WordPress files through SFTP in the control panel.
  • Now deactivate each one of your plugins. Also, you may do this by just renaming the name of your plugin folder into something else.
  • Also, you may delete all the files, causing them to deactivate, and store the backup of these files at some other place, as the first thing. Once all these files are deleted from the actual folder, you may restore the saved plugins in the very same folder. This will put back the data on your server instead of reactivating them.
  • As you deactivate all the plugins, you should be able to access the WordPress and log back into it to follow the above-discussed process. But if you face the same white screen even after clearing your cache that this means that the guilty party is your theme.
  • As you have figured out the real problem, deactivate your WordPress theme. For this, follow the same process of renaming your theme folder and re-uploading the files in the same folder, after first deleting them. This will enable you to access the WordPress again, and from there, you can then switch the theme.
Ways to Avoid WordPress Plugin Conflict Shortly

By far, you must have had an idea that cleaning of WordPress plugin conflict is not that difficult. All you need for this is a little bit of patience and time to figure out the problem source. As you complete the troubleshooting, the fix is then easy enough to execute.

With that said, time is money. Where as you may find all of these WordPress issues as an easy fix, or not to difficult to resolve, why suffer from these issues when you don't have to! The time that you spend on fixing these issues can instead be paid in building more sites or even in making your business process smoother.

Therefore, to avoid these hectic issues or hassle altogether, following are some useful and handy tips, which you may include in your business processes to help yourself and your customers in avoiding WordPress plugin conflicts from now onwards:

  • Do not download or install a WordPress plugin on a whim. The fewer amounts of plugins you add to your WordPress, the fewer numbers of problems you would face. To put in simple words, you can easily avoid running into these troubles. So, make sure to decide WordPress plugins wisely.
  • Before you activate or install a new plugin, make sure to go through the support tickets or read the plugin reviews. Take out a reasonable time for this activity as this can save you a lot of trouble in the future. However, if you don't have enough time to review these details then do take a recommendation from any of the trusted 3rd party or maybe a tech blog to choose only the right one.
  • Keep all the plugins updated to a recent version, at all times
  • To identify the troublemaker, update one plugin at a time. Even though this might not be convenient to handle the updates, but this will help you in determining the troublemaker plugin efficiently.
  • In the case you prefer an automated updating tool, ensure that it also runs a backup as the first thing and utilize the facility of safe upgrade such as Automate.
  • Do check your WordPress plugin set every after a few months. If you come across any plugin that might have lost updates or developers' support for more than five months around, look for a new one.
  • Ensure to back up all the data before installing or updating a new or existing plugin

  • You may duplicate your WordPress site by using a local testing environment. This will help you in testing updates or new plugins for any of the potential conflicts, before actually incorporating them on your WordPress site.
  • Brush up on the coding standard guidelines of WordPress Codex. Even though you may not need to develop themes or plugins for your site, understanding this can still help you in knowing good coding practices, in case, you inspect plugins prior using them.
  • Also, do acquaint yourself with hooks at some time. Usually, the plugin conflict arises when developers fail to provide their hooks with an exclusive name. As they go with a default hook, they typically run the risk of conflicting or using a hook which is already used by some other theme or plugin. This eventually confuses the server and causes conflict error.
  • Similarly, brush up your PHP, HTML and JavaScript skills. However, if you feel overwhelmed by so many conflicting plugins, you may code this functionality into your WordPress and do away with this issue from now onwards.
Summing Up

Of course, there are many ways to be smart enough regarding using and activating plugins on a WordPress site. It is, however, recommended to use a single trusted developer to get all the required plugins for your WordPress site. That is instead of collecting speed optimization plugins from one developer and collecting analytics plugin from another developer; your best bet is to get all the plugins from one trusted provider.

Moreover, as mentioned earlier, don't forget to take recommendation or consult support team before incorporating a plugin into your WordPress and to avoid conflicts. The best way to prevent WordPress conflicts is by carefully choosing only the right plugin for your website. Additionally, you must remember that plugins are merely WordPress functions' extensions. This means, they should only be utilized sparingly or whenever necessary.

While this is inevitable that you won't experience a plugin conflict at least once during the lifetime of your WordPress site, it won't be a problem for you if you are familiar with its easy fixes like shared above. However, if you are using WordPress plugins to perform simple tasks, the smarter approach would be to learn the ways to replace these with more custom codes. For this, you may discover it yourself or take the assistance of a developer to write those specific codes and include them in your theme.
