Hello, I am trying to install a test site of IPB 4 but I can´t because I see this error:

Forbidden

You do not have permission to access this document.

Only in IPB 4 because with IPB 3 it´s all ok.

Thanks!

Check your server directories permissions, file permissions, open_basedir and also your error.log and please report back
