I have two questions about my site.
1st - When I try to login in my forum, I can't. It just shows me a blank page.
2nd - Do I need to write everything in English? I wanted my site to be just portuguese...
Currently x10hosting only accepts sites that are in English, Spanish, or French.
It is already in PHP v2.Upgrade your account to PHP v2 in the account panel. That should fix your "white page" problem.
Then my site is ok?Your site must mainly be in English, Spanish, or French. Your site can have content that is not one of these three languages, but its "main language" must be on the three.
