yeah it not a problem. It occured for me when copying a template, but I removed the template with the problem and tried it again and it worked.

Apache has a lot of security features too, and I have to say flexicontent is one of a few joomla components that actually get along with it. An error like this is hardly an error, true. And it only occurs when copying a template so no biggy
