We have a static post carousel on our home page that was working until we upgraded to PHP 8.2.2. We only updated because we though we should be on the current version of PHP. By “not working” I mean there is extra content and missing content. We also get an error message whenever I click Appearance/Widgets:
The “custom_html” block was affected by errors.
In addition to the error message, the site becomes either inaccessible by anyone or my IP gets blocked (which I fixed by white listing myself). I do not know if there is any connection between the carousel problem and the Custom html error message.
I am at a loss to troubleshoot this. Thanks you.
