Critical error when updating to 6.5 version

Hi magick207,

The critical error is typically caused by problems with PHP, exceeding memory limits, code errors, or issues with plugins or themes. Here is an article that provides detailed instructions to troubleshoot the issue:
https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-critical-error-in-wordpress/

Alternatively, you can enable WordPress debugging mode or check server logs to see if anything gets logged there. If you’re unable to locate the logs, please contact your host support to help you with this.

Hope it helps!

Hi @saniamohammadi,

thank you for your reply. I have tried again deactivating all plugins and now I don’t have a critical error page, but a blank page. I have activated the debug mode and it shows me this:

Fatal error: Cannot redeclare wp_queue_comments_for_comment_meta_lazyload() (previously declared in /home/[account name]/public_html/wp-includes/comment.php:540) in /home/[account name]/public_html/wp-includes/deprecated.php on line 4663

Fatal error: Uncaught Error: Class “WP_Translation_Controller” not found in /home/[account name]/public_html/wp-includes/l10n.php:796 Stack trace: #0 /home/[account name]/public_html/wp-includes/l10n.php(953): load_textdomain(‘default’, ‘/home/[account name]…’, ‘it_IT’) #1 /home/[account name]/public_html/wp-includes/class-wp-fatal-error-handler.php(46): load_default_textdomain() #2 [internal function]: WP_Fatal_Error_Handler->handle() #3 {main} thrown in /home/[account name]/public_html/wp-includes/l10n.php on line 796

Thank you again.

Please attempt to switch to the default Twenty Twenty-Three theme. If the problem goes away, then the main issue is with your theme, and I recommend contacting its support.

If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to deactivate all plugins and change the theme for you while you’re still logged in without affecting normal visitors to your site.

Hi,

as I say in the first post, I have already tried to switch the default theme. In any case, I was able to update using Softaculous.

Thank you.

Still no solution for this?
