Topic: Silly bug :P
I ran into a problem today while creating a new forum. https is the ONLY way to access my site. After a fresh install of punbb 1.12.14 the basedir was set to http://addresses. It took me about 30 minutes looking over the str_replace + preg_match in confirm_referrer before I suddenly realized it wasn't doing anything to the http:// part of the address. So the code that for whatever reason removed the https:// part of the address during install should be updated IMHO :P
Also, while fumbling around my problem I came across another bug, but the private security related submit thing isn't working. I can't think right now due to a hangover, so I'm unsure if it could be used to do anything... at all, but I'm sure functions are there for a reason... :P
