    Hello, I am getting a critical error when submitting a comment on a blog or podcast post.
    I am able to access the rest of the admin site, only occurs on posting the comment.
    I enabled debugging, and got the following information, this occurs on the wp-comments-post.php page after hitting submit. I’ve tried restoring a back-up but that didn’t work.
    Any ideas where to start to fix this? I’m thinking maybe something to do with the php-mailer since the comment actually goes through.

    Thank you!

    This may be a plugin or theme conflict. Please attempt to disable all plugins, and switch to the default Twenty Twenty-One theme. If the problem goes away, enable them one by one to identify the source of the problem.

    If you can install plugins, install 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.

    Thanks, was trying that, however I am seeing larger problems now with random images disappearing, not all, just some… site logo, slider images, some case study images, some older blog images… very strange.
    I have updraft backup, but restoring didn’t help (and still kept the wordpress update), I also have BackUpWordPress backups, what’s the best way to revert to one of those, just ftp files over and overwrite?

    Check the documentation for the backup plugin for their specific recommendations on restoring.

    I have tracked down this critical error to the updating of my WordPress version.
    I reverted to back-ups prior to the update, and everything was working correctly.
    Once I completed the WordPress update again, I got the same error.
