Hello @cfarbes,

Thanks for writing to us.

It might be the issue of version compatibility. Please make sure your theme, plugins, WordPress, and the PHP version(7.4) are updated as per our version compatibility page.

You may check out this article, it is also recommended by WordPress as well.

Hosting Requirements for WordPress

I would suggest you please purge all the cache. I would suggest you troubleshoot a few of the common issues before we investigate your settings.

1. Testing For Theme Related Issue
2. Testing For Plugin Conflict
3. Theme Update
4. Child Theme
5. Css/Js Customization
6. Increasing Php Memory Limit
7. Disabling Cache
8. Disabling Cdn
9. Permalinks
10. Version Compatibility

If none of those work, It would be best if you could copy your live website to your staging area. and send your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details

• WordPress Login URL
• Admin level username and password
• FTP Details

You can find the Secure Note button at the bottom of your posts

Thanks
