I tried changing the fb_rules.php file to put custom rules, but I accidentally deleted a part of it that needs to be there. I don't remember exactly what it said, but the url is zoekidsclub.com/index.php?option=com_fir...id=10&func=rules

If you could maybe point me to where an original copy is? Much appreciated =)

you don't need to edit this file, simple in joomla! make new article
Admin Panel >> Content >> Article Manager >> New

write your rules
in article setting (this article)
Title : aniting
Section : Uncategorised
Category : Uncategorised
Published : No
Front Page : No
Access Level : Public

Save your article and go to Article Manager to find the ID for this article

new go to Components >> FireBoard Forum >> FireBoard Configuration

search "Rules Content ID"

be Default = 1
replace 1 with the ID of your article

In case anyone had been monitoring this, I found a replacement fb_rules file when i was looking through the fireboard download. It's in the sources folder. I replaced it and just experimented with where I put the rules in the file and it works fine now. Thanks for the suggestion though =)
