I had the same problem with the filter getting turned off and not working. There's an error in the code in the installation file..
In "root/member.php" where it says to add:
PHP Code:
// User-Selectable Optional Language Censor by 006
$swearfilter=iif($swearfilter=="yes",1,0);
Under:
PHP Code:
$options+=iif($showimages=="yes",4,0);
Add This Instead:
PHP Code:
// User-Selectable Optional Language Censor by 006
$usecensor=iif($usecensor=="yes",1,0);
Basically, if you've already installed this hack.. Just replace both instances of "swearfilter" with "usecensor" in that line and you should be all set.
