I am setting up a web site for a student government group that has new elections each year. I'm trying to make it so that each year, the new group can archive the previous year's discussions and have a fresh install of phpbb.
To that effect, I've set up a directory structure like http://foo.com/forum/10, where I've installed phpbb, and it's working. I'd like the same site to appear at the URL http://foo.com/forum, so I added a .htaccess file at /forum with "DirectoryIndex 10/index.php" in it (no quotes).
Next year, I plan to make a new install of phpbb at /forum/11, and I'll change the .htaccess to "DirectoryIndex 11/index.php"
The problem is that if I go to http://foo.com/forum/, I see the contents, but no style sheets work. It does work if I go to http://foo.com/forum/10.
I suspect this is because phpbb uses relative urls throughout ($phpbb_root_path appears to be widely referenced), so the style isn't loading correctly.
Is there a good way for me to define $phpbb_root_path with an absolute path rather than a relative path in phpbb?
Or is there a better approach to this problem than what I'm trying?
Thanks in advance!
