I'm not sure if this is a XenForo issue or a server misconfiguration. I have moved my forum to a new server , it works but when I try to upload a image I see this (forum is closed until I resolve this)
Please can you help? I have not found the solution and I'm a bit desesperate, I don't want to get back to the old server.
I can see images uploaded previously.
UPDATE: I think it's a php-gd problem.
