    I tried updating two of my Wordpress installs to the latest package (v3.0.0), and it results in a critical, not very verbose, error message.

    "There has been a critical error on this website.
    
    Learn more about troubleshooting WordPress."
    

    I tried renaming the entire plugins folder while in recovery mode, in order to find out whether it's a specific plugin, but the result is the same.

    Any ideas what might be going on here?

    @stormgrass PHP got upgraded to 8.1, make sure your plugins and themes are ready for that before updating.

    Sounds like it's probably a theme then.

    @jdaviescoates Thank you! Apparently it was one of my plugins, but they needed to be deactivated manually, simply renaming the folder didn't work. I guess I'm gonna do that with my other installs now and see which one it is there that breaks the site.

    I've had this happen to me. The quickest for me was to just restore from the most recent working backup. You are backing up, right? And yes, as @jdaviescoates says, it's definitely a plugin or theme not ready for 8.1. I suggest restoring to one of your backups, and work from within the functioning WP to deactivate the problematic plugin/theme, then upgrade.

    @stormgrass You have to go to wp-config.php and enable DEBUG mode to understand if plugin or theme is blocking.

    Insinde wp-confing.php you will find:

    define( 'WP_DEBUG', false );
    define( 'WP_DEBUG_LOG', false );
    define( 'WP_DEBUG_DISPLAY', false );
    

    change to

    define( 'WP_DEBUG', true );
    define( 'WP_DEBUG_LOG', false );
    define( 'WP_DEBUG_DISPLAY', true );
    

    And you will see on the screen what is blocking your Wordpress instance.
