WPBakery Page Builder is not working with WordPress 5.5

Hi, if you are reading this post, it means that you have problems with starting up the WPBakery Page Builder editor on your WordPress website.

What does the problem look like?

I have stumbled upon the same problem: all of my website’s pages that were built with this wordpress plugin failed to load. When trying to edit a page contents from the backend, the editor would load as the most basic code editor, and the visual editor could not be enabled.

I have also tried editing a page from the frontend visual editor which would load a page, but not completely – the page was whitish and still not editable.

How I tried to fix the problem

Of course, first thing I googled it and there were similar cases related to the WordPress 5.0 version. But since the new WordPress 5.5 version has been just recently released, there are yet as of now no mentions on how to fix the issue.

So, first thing, I would recommend you to do the procedures recommended in the old posts, and it may actually solve your problem with the WPBakery Page Builder not loading properly:

1. Make sure you have the latest version of the WPBakery Page Builder plugin installed. I beleive, this plugin will soon receive an update from the WPBakery support team.
2. Try to install the Classic Editor plugin and enable it in the General->Writing menu. For some people on WordPress 5.0 it was the solution.
3. Try to resave the settings of the WPBakery Page Builder ‘Role Manager’. Edit something and save, then reverse the edits and save again.
4. Disable your WordPress plugins one by one and check if the WPBakery Page Builder is loading fine.

I have done all of the above and still the problem loading the plugin was not resolved.

The ultimate solution [fix] for WPBakery Page Builder under WP 5.5

Now, if nothing of the above have worked for you. The only thing left to consider is to actually downgrade your WordPress 5.5 back to say the last stable version which currently in 5.4.2.

There are basically two methods to downgrade the WordPress. You can download the WordPress 5.4.2 distribution package and install over the current, by uploading and extracting the archive on your hosting. But that’s the worst case scenario. So, here is the most simple and hassle-free option:

1. Download and activate the plugin WP Downgrade.
2. Go to the plugin settings (Settings -> WP Downgrade) and input the version 5.4.2 and click Save changes.
3. The page will refresh and suggest you to go to the Dashboard -> Updates. There you need to click on Re-install to version 5.4.2
4. Done!

From this point, check if the WPBakery Page Builder is loading properly by editing one of your pages/posts.

Let me know in the comments if this method worked for you.

Thanks!
