If you found like this issue, try change web server to other (let say nginx-proxy mean nginx+apache; so change to lighttpd) and then change back to previous (let say nginx-proxy). The same ways to php-type where change to mod_php_ruid2 and then change back to php-fpm_event.
To make sure, try 'sh /script/fix-skeleton; sh /script/fix-chownchmod; sh /script/fixweb; sh /script/restart-web -y'. If found error in restart, try reboot.
