 * Hi, I updated to PHP 7.4 and all my subpages show an error message on the top.
   Message remained after downgrading to previous PHP, now it´s set to 7.4 again.
   
   Divi developer also stopped working, as well as Webba booking interface. Help,
   please…

 * 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](https://wordpress.org/plugins/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**.

 * Hi James, looks like it worked, the error message dissapeared when I switched
   to another theme and back, and the interface of the plugins also started working
   after being disabled and enabled again. Thanks a lot!
    My Events manager still
   seems to be having problems allowing Divi layout for new events, but I can go
   around it for now.
