I tryed installing the xenforo license and I get 500 internal server error.
I followed your install guide http://xenforo.com/help/installation/
I don't quite understand the file permission part. I know that it has something to do with the wrong permissions but I am not quite good at that part.
What I did was downloading the Xenforo zip from the client area.
Then I uploaded the zip - Extracted it and I got that. I can't even access the /install/ part.
Please help me with any kind of response.
