I am having trouble install a phpbb forum. Under your Sub Domian it asked under the box where it asked you would like to Install it to I have no indea what to put in that box.
Login to your account panel: http://x10hosting.com/login with your FORUM user\pass. Once logged in there is a section on the left to request the new version of PHP. Request Version 2(Intermediate).
ok what it is asking is if you would like to install it into the root directory or a specific folder within the subdomain so basicly if you want to install it with a home page before the forum use a folder like "/forum" otherwise you can leave this blank
