    I have updated wordpress to 5.5 and I just get a critical error when the website loads. I tried enabling jquery migrate but that doesn’t do anything, same error.

    I have to restore wp-includes and wp-admin folders from backup to get the site working again.

    Not sure what to do 🙁

    Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

    I always have to manually update as the auto one stopped working since the last update. I tried renaming the active theme but I just get the same critical error when loading the site.

    I tried adding the debug code into wp-config but it doesn’t seem to generate any debug.

    all plugins were disabled when I did the update.

    I even tried renaming the plugin directory but still the same issue. Not sure what to do.

    If the errors continue with both plugins and the theme reset, try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), and delete then replace your copies of everything on the server except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings.

    Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

    I deleted wp-admin and wp-includes directory completely and uploaded new files but exactly the same error occurs.

    The only way the site can be fixed is if I upload the previous wordpress wp-admin and wp-include folders.

    When debug is enabled in the wp-config:

    define(‘WP_DEBUG’, false); change to define(‘WP_DEBUG’, true);

    You’ll find error logs in these locations:
    /public_html/error_log
    /wp-admin/error_log

    I was being an idiot. I didn’t copy the root files in the wordpress 5.5 update.

    site loaded however revo slider didn’t work but I enabled jquery helper and that fixed this problem.

    its the wp-bakery page builder, no idea what to do as that is integral to the site.

    Enable wp_debug in the ‘wp-config.php’ file.

    define(‘WP_DEBUG’, false);
    change to
    define(‘WP_DEBUG’, true);

    Look for error logs in these locations:
    /public_html/error_log
    /wp-admin/error_log
