Sorry to hear about the issues with PHP8. We are using PHP8 on our server and there is no issue with the Catch Responsive Pro version 4.7.8. Can you check for an error log or contact your hosting server to find out which code has an issue? Sometime, it might be the server and WordPress configuration issue.
Also, can you try activating a different theme to check?
Finally my husband found out was was wrong.
In the last line of the wp-config.php two speech mark were missing. It was minor instead of ‘minor’.
I have no idea why or when these two got lost – but now I was able to change to PHP 8 and the website it’s running fine agein.
