I am trying to install phpBB3 on my site. I go to the install folder at /phpBB3/install/index.php and it just gives me a blank screen. It is supposed to show the phpBB3 overview and installation home page, but all I see is white.
You may need to upgrade your php account to intermediate. See this thread for an explanation. You can request an upgrade in your account panel. Wait 12-24 hours for it to take effect.
