Re: Fatal Error?
You have the wrong URI in your config.php. You have this (I think):
// The full URL of your bbPress install
$bb->uri = 'http://ironboundforum.com/forums/';
and it should be
$bb->uri = 'http://ironboundforum.com/';
bbPress doesn’t care if it’s in a folder or not, just like it doesn’t know that it’s in your webroot of /kunden/homepages/46/d93680635/htdocs/ironbound/, so that ‘forums’ portion does not need to be in the config.php for your URI.
See this after I applied the proper stylesheet:
