Upgraded to PHP 7.4 and now I can't edit my pages

My website was built on WordPress using XTheme Pro. To make sure I’m using the latest and greatest, I wanted to move my site over to PHP 7.4. I made backups, downloaded everything there is to save, and made the change.

Now, I can edit any and everything except my page content. My theme just gives me the spinning wheel of death. Any suggestions?

Sounds to me like your theme is not compatible with PHPv7.4…I would try rolling back your PHP version. I believe most themes currently support up to v7.3, but not all have 7.4 compatibility yet.
