Hello Team,
I tried to update my WordPress site to the latest 6.1.1 version. But this update failed and I could not access my site as it started giving critical errors.
It was complaining for,
PHP Fatal error: Cannot redeclare wp_get_attachment_thumb_file()
To Solve this I restored the wp-include folder and then the site was accessible.
But now I cannot login to the admin page due to the below error.
PHP Fatal error: Uncaught Error: Call to undefined function use_block_editor_for_post_type()
Could you please assist here with solving this issue?
