4 Free Plugins to Test Your WordPress Site for Compatibility Issues

Creating a website with WordPress can be a challenging and sometimes frustrating pursuit, especially when you’re working with plugins or themes. You run into compatibility issues, which may break your site.

That’s why it’s a great idea to test your site for errors before implementing any changes.

Posting a copy of your theme, plugin, or site files on GitHub for community feedback is one way to solve issues before they cause problems. Unfortunately, you may have to wait a while for replies, and fixing issues could take a bit as a result.

Luckily, some free plugins do a fantastic job of quickly helping you test various aspects of your site so you can catch any issues before pushing your content live.

The plugins in this collection allow you to do everything from instantly checking plugin’s compatibility to cloning an entire site and ensuring your theme meets WordPress standards.

  • Theme Check

    This plugin is sure to delight any theme developers out there. Theme Check runs the same automated testing on your site that the WordPress Theme Review team uses. The latest theme review standards are integrated to ensure your theme either meets or exceeds WordPress best practice. This plugin is also compatible with Multisite installations.

    All you have to do to test your theme is to go to the Appearance tab in your admin area, then click on “Theme Check.” From here, all you have to do is simply select an installed theme from the drop-down list and click the “Check it!” button. One step short of instantly, you’ll see information about the selected theme alongside a “Pass” or “Fail” notice.

    Now you don’t have to worry about implementing or uploading a broken theme. It takes seconds and you’ll save a ton of time.

  • Duplicator

    With the Duplicator plugin, you can pull down a live site to localhost for development. This way you can test out the compatibility of all that you have installed in your WordPress site on the localhost before making it live.

    Plus, you can manually back up a WordPress site (or parts of a site), duplicate a live staging area, and bundle an entire WordPress site for simple reuse or distribution.

    This is a free plugin to use, has a 5-star rating, and has over 20-million downloads. It’s worth trying for when you want to test your website on a local environment and more.

  • NS Cloner - Site Copier

    The NS Cloner plugin copies your website’s content in its entirety to prepare it for testing. The difference is that NS Cloner only works with Multisite installations. The plugin needs to be network activated and it doesn’t just allow you to manually copy the content to a new install, but actually creates a copy automatically.

    While this is a fast, efficient, and great plugin by itself, it’s not without its problems. There are known issues with this plugin; specifically, NS Cloner only works with your main site and not any site in your network, it doesn’t work if you changed your database prefixes from the default wp_ setting and isn’t 100 percent compatible with BuddyPress.

    If you want an incredibly fast plugin like the NS Cloner that doesn’t have these restrictions and has even more features, check out our own legacy plugin, Cloner. It’s a viable and recommended alternative to the NS Cloner plugin.
