Ways to Fix WordPress Conflicts

Pre-Conflict Measures in WordPress

Before applying changes to a live WordPress site, ensure you’ve tested things on a staging website. This will help you determine if a new change will affect your business site.

A staging site represents a clone of a WordPress site – used to help users test new updates, scripts, or programs on a WordPress infrastructure before applied on a live website. Once a change doesn’t affect a staging site, you can apply changes to a business infrastructure.

Creating a staging site is accessible in WordPress. If you have a hosting plan and a domain, you can make a copy of a business site you own, referred to as a staging site. You can also use a Tool that helps you create a staging site online.

Isolation of Themes and Plugins

If you think – a specific theme or plugin is causing conflicts, you should isolate WordPress themes and plugins – one by one.

This helps you see if you can spot conflicts caused by specific agents, allowing you to track, make changes, and finally fix conflict issues in WordPress.

For example, if deactivating a specific theme or plugin solves a problem, you can conclude that keeping the culprit agent off the site may help solve performance issues in WordPress.

Let’s learn how isolating WordPress themes and plugins can help solve conflict issues in WordPress.


Head over to the Appearance -> Themes page in the dashboard and deactivate the currently applied theme. After deactivation, you should activate a default WordPress Theme, such as Twenty-Twenty Three.

Next – clear browser cookies and see if the change has made any difference.


Deactivating WordPress plugins one by one may solve performance issues in WordPress.

In this case, head to the Plugins page in the dashboard and deactivate each plugin individually.

Here – you should observe if the changes are making a positive difference to WordPress.

WordPress Updates

WordPress updates may create conflicts between WordPress themes and plugins.

For example, when a theme or plugin is updated, improvements in new functionality can create conflicts between existing assets in WordPress.

First, you should turn off the automatic updates in WordPress. In this case, make sure no theme or plugin updates automatically. When manual updates are enabled, you can see if updating a theme or plugin on a staging site creates problems.

Let’s learn how to set updates for WordPress assets.


You should check if a premium plan supports automatic updates if you’re using a premium theme. If yes, you should check if turning off automatic updates is possible in WordPress.


Similarly – head over to the Plugins page in the WordPress dashboard and set manual updates for all plugins. When a new update is available for a theme or plugin, you can see updates on the WordPress Updates page in the dashboard.

Use Multi-purpose WordPress Plugins

If using specific plugins that provide different functionality is undisputable and causes conflicts, find a single plugin that fulfills multiple functionalities.

For example, instead of using several plugins for security, backups, and speed, JetPack helps you use all features collectively.

No doubt – using a single plugin for more functions helps users avoid conflicts in WordPress.

Wrapping up

You can avoid WordPress conflicts if you know how to keep WordPress error-free with backend infrastructure, WordPress manual improvements, and periodic maintenance.

In this case – don’t leave WordPress assets unattended, such as letting WordPress update plugins automatically.
