NamelessMC

I resolved the problem, sorry for taking up your time.

The problem was that I changed the name of the template.

I know someone opened a topic, but he didn't specify how he managed it. So I get this error: The Error

I did it and now works.

I deleted in .htacces the Option -FollowSymLinks, and now I get an error which I cannot solve.
The Error:
