Subdomain redirection fail

Hi all,

I've problem with my subdomain, when I want to view http://forum.espace4you.org , I've this error :

Code:

Forbidden

You don't have permission to access / on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

But if I use it http://www.espace4you.org/forum/, it work fine.

It worked fine when I use ISPConfig 2.2.10, but when I upgraded in ISPConfig 2.2.12, My server return this error.

Have you an idea ?

Thanks for your answers

 

Ok thanks, but this morning it work fine and actually it doesn't work. Is it possible to come in Apache url rewriting ?
