Hooray! WordPress 5.4 “Adderley” is here! But OMGWTFBBQ!? Everything is now broken?
Don’t Panic!
Before you go any further, make sure you’ve updated your plugins and themes to the latest versions, clear your browser’s cache and cookies and re-log in to your WordPress dashboard.
The New Editor can be disabled!
If you’re in a pinch and need the editor rolled back ASAP, please install the classic editor – wordpress.org/plugins/classic-editor – which will restore the old editor.
Still having problems? Okay, read on!
This thread contains the known issues with plugins and themes found in the latest release. Please read this WHOLE topic and come back and check again later, as it will be updated.
Remember to be calm, be patient, and be respectful. Volunteers are out here to try and help you, but we need your help too. All of the normal forum rules still apply. Remember, you are just as important as everyone else.
If your post doesn’t show up right away, please be patient. With the higher than normal post volume, more posts get flagged as spam by our auto-spam tool. We’re working hard to keep the queue clear, but making multiple posts slows us down, as we have to go back and check if you already posted. Post once.
- Do use proper capitalization in post titles and body. Punctuate your sentence properly and humanely, it helps us read.
- Do use descriptive subject lines. “All permalinks broken since 5.0” is much better than “Augh! Help ASAP! This version is terrible!”
- Do describe the problem clearly. Explain what you’re seeing, include error messages and link to screenshots if needed. Linking to your site, if the problem is on the front-end, also helps.
- Do be patient. We know it sucks to be down, but posting multiple times doesn’t get you help any faster.
- Do make your own topic unless you are using the exact same version of WordPress on the same physical server hosted by the same hosts with the same plugins, theme and configurations as the original poster. You may find it weird, but it will be easier for us to help you specifically if you have your own topic.
- Do mark your topic as resolved when it’s fixed so we know not to come looking there anymore.
- Do remember you’re not alone.
Also keep in mind that not liking the direction of WordPress’s design is not a bug. If you don’t like a feature, please don’t make a series of posts complaining about it. Look and see if someone already did, and post there, or consider joining the process earlier on (like in Beta or even test via SVN). What you’re seeing today is the result of thousands of hours of work and testing, and unless something is outright broken, it’s highly unlikely to be changed.
Again, before you post:
Make sure you’ve read this entire thread and New Features in 5.4 Article.
Go to your own install’s about page –
example.com/wp-admin/about.php(or click the WordPress logo in the top corner) – to see what’s new.

Before posting, please make sure you’ve tried started by performing the troubleshooting steps outlined below:
- Flushing any caching plugins you might be running, as well as server and/or browser caches. Not just your browser, but any op cache or content network cache as well such as Cloudflare. That will solve many weird JavaScript issues.
- Flushing Managed host caches. Managed WP hosting often has special caches. If your host has a “Purge Varnish” or “Flush Memcache” tool, try that. You can ask your provider to flush memcache and Varnish for you if necessary.
- Resave your Permalink settings. In a few cases, we’ve seen third-party installers, such as Softaculous, creating sites with slightly incorrect rules in the .htaccess file. While these rules would not have been a problem in previous versions, having these incorrect rules can break the REST API in newer versions. Resaving the permalinks on the Settings->Permalinks page in WordPress will fix these rules in the .htaccess file, and possibly fix “failed” errors in the new editor.
- Troubleshooting with your browser. Your browser can help you identify JavaScript issues or conflicts and this article can assist you in doing that diagnosis. This could help identify Visual Editor issues as well.
- Make sure you have the Visual Editor enabled. Visit your Users->Your Profile page. The first option will disable the visual editor. Make sure that option is unchecked, and save your profile settings.
- Deactivating all plugins (yes, all) to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s). If you can’t get into your admin dashboard, try resetting the plugins folder by SFTP/FTP or PhpMyAdmin (read “How to deactivate all plugins when you can’t log in to wp-admin” if you need help). Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to
mu-plugins-old - If you can install plugins, install “Health Check”: wordpress.org/plugins/health-check. On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.
- Switching to the current default theme to rule out any theme-specific problems. If you can’t log in to change themes, you can remove the theme folders via SFTP/FTP so the only one is
twentytwenty. That will force your site to use it. - Manually upgrading. When all else fails, download a fresh copy of the latest.zip file of 5.4.* (top corner on this page) to your computer, and use that to copy up. You may need to delete the wp-admin and wp-includes folders on your server (NOTE: do not delete the wp-content directory or your wp-config.php file) Read the Manual Update directions first.
If you need to create a support topic, you can provide debug data for the support volunteers by visiting the Site Health section under
Tools>Site Health>Info.This section contains noteworthy (high impact/large) plugins with compatibility issues, and their responses when available.
- KingComposer – infinite load on editor page.
Update of the plugin has been released version 2.9.2 - The AMP plugin had an issue that could cause reusable blocks to be deleted. This is not directly connected to WordPress 5.4, but it happened in the same timeframe. To solve, update the plugin to version 1.5.1.

- Preview of blocks in the Block Editor has errors with current version of Hestia theme. See: https://wordpress.org/support/topic/problems-with-blocks-in-hestia-after-wordpress-updating-to-wordpress-4-5_nl/ <br>An update of the theme has been released that hopefully solves the issue, see comments under he linked post.
- Some non-free themes from paid sources cause minor incompatibility issues with the latest version of the block editor. These can manifest as “This block has encountered an error and cannot be previewed”. Go to where you purchased your theme, and download an update for it. The marketplace where you bought the theme may have an update plugin you should use to keep the theme up to date.
- Stargazer (free) theme not compatible with the block editor
