How to Test for Theme or Plugin Conflicts

Have Nelio Popups presented any unforeseen problems for you? For maximum compatibility with WordPress sites, our plugin adheres to best standards. A theme or plugin conflict, however, can occasionally occur because other developers don’t adhere to these standards or because other unanticipated problems arise.

This article will demonstrate how to find and resolve theme or plugin issues.

Checking for Plugin Conflicts

The majority of plugins require additional resources to function effectively, including JavaScript files or CSS stylesheets. But occasionally, the code from these files will modify things that aren’t in their intended context and break or affect functionality.

You should be able to establish whether the problem you’re having is the consequence of code from another plugin by following the steps listed below.

1. Back up your Site

Make a backup of your website before you start. Before making modifications to your theme or plugins, it is always a good idea to take this precaution.

2. Deactivate All Other Plugins

Go to the Plugins page once you’ve finished backing up your website. You must choose all of your plugins there, excluding Nelio Popups (and Nelio Popups Premium). Then select Deactivate from the Bulk Actions dropdown menu at the top of the page.

Deactivate all plugins.
Deactivate all other plugins.

WordPress will simultaneously deactivate each of the selected plugins when you press the Apply button.

3. Reactivate Plugins and Monitor the Issue

Check to see if the issue still exists after deactivating all of your plugins except Nelio Popups. If the problem persists, you’ll know there was no plugin conflict and therefore can check your theme.

If the issue is fixed, however, the next stage is to identify which specific plugin was provoking it. You’ll need to individually reactivate each plugin to accomplish this.

Reactivate all plugins.
Reactivate all plugins.

Check the problem again after each plugin activation. The simplest way to do this is to maintain two browser windows or tabs open, one showing the Plugins page and the other showing the location of the issue.

You’ll be able to identify the conflict as being caused by the most recent plugin activated when the problem reappears.

Checking for Theme Conflicts

The next step is to determine whether the problem is related to your site’s theme if the problem still exists after checking for plugin conflicts.

You must switch to a default WordPress theme in order to check for theme-related issues. They are all given year names (Twenty Twenty, Twenty Twenty-One, etc.).

These themes are suitable for testing because they adhere to strict standards and are quite simple. Consider switching to a theme you’ve never used before if you’re already using one of these.

Go to “Appearance » Themes” when you’re ready to change your theme. From this point, select “Add New” and look for “Twenty Twenty-One” (or one of the other recent default themes).

Add a new theme.
Add a new theme.

Then click on Install followed by Activate.

Install a new theme.
Install a new theme.

You must attempt to reproduce the problem once the default theme is enabled. You’ll know the root of the issue is your default site theme if the issue is fixed after installing the new theme.

What to Do After Locating a Conflict

There are two things you should do if you’ve determined that a plugin or theme is to blame for the problem you’re experiencing:

1. Contact the Plugin or Theme’s Support Team

It’s critical to communicate your findings to the team working on the problematic product. In many cases, the author or support staff will already be aware of the issue and may even have a solution to offer you.

2. Let Our Team Know What You’ve Found

We sincerely appreciate you taking the time to inform us of any issues you run into and any fixes you find. Your information can help others who are having the same problem and our support staff can share what you’ve learned with them.

Sometimes we are unable to resolve problems caused by third-party code, such as themes or other plugins. You’ll need to get in touch with the conflicting plugin or theme’s support staff to do so, as was already explained.

All done! We sincerely hope that this lesson has assisted you in identifying any theme- or plugin-related issues on your WordPress website.
