SOLVED Permission Denied after moving to apache worker

Hello,
Yesterday i configured the easy apache to use the Worker MPM instead of prefork one for my wordpress site,

But then i found that the "public_html" folder group ownership changed to "nobody" group!, and the plugins can't write to the home path as usual,

When i tried to change it back to the default group "same name as user", the site gave me
"
Forbidden
You don't have permission to access / on this server.
Server unable to read htaccess file, denying access to be safe

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
"
And apache logs showed: "
(13)Permission denied: [client a.b.c.d:51198] AH00529: /home/User/public_html/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable and that '/home/User/public_html/' is executable"

Any help please?

 

Solved, thanks to cpanel support center, adding suexec module to cgi php handler did the trick,
