File not found error

[yehudigt]

As of yesterday's update in plesk 12.x All htaccess rewrited pages are returning a File not found Blank Page.
Server info: 12.5.30 CentOS 7 1205160407.13
Php V 5.6 as fast-cgi

I think this problem can be avoided if I switch back php to run as apache module. But this isn't showing anymore in my plesk control panel under php settings. Can anyone help?

Thnk you

Another hint could be that this domain is a subdomain (not under httpdocs dicrectory) - Other web sites under httpdocs are working correctly
