CWP7.PRO - REST API - 404 not found (caused Wordpress not working

Hi there,
Im runnung CWP7:PRO on my server and my hosted Wordpress instalations (new and updated) had errors with REST API. It returns a 404 Not found error, which is going to break a lot of functions on the WP sites. Could anyone help me please?

Send some REST API request and then check error logs of the sites and webserver:
/usr/local/apache/logs/error_log
/usr/local/apache/domlogs/DOMAIN.error.log
to investigate problem.

Which version of PHP are you running with your WP sites? Some newer versions (8.2+)  are not fully compatible with WP yet... even 8.0 and 8.1 have some compatibility exceptions:

Thank you, good question, i use PHP version: 8.1.7

Does your answer mean "the problem is solved" ?

Hi, no, it is not solved for now, im still searching the cause and sollution...
