It doesn't seem to be a problem here, but it is elsewhere - the RSS Feeds for Categories and for the whole forum doesn't show the proper number of items.

Now, there doesn't seem to any particular rhyme or reason to this. Sometimes changing the RSS settings seems to fix it - and sometimes not. Sometimes refreshing the browser cache seems to fix it.

Here is a fix for testing: In RSS.pm find

            $threadcount = @threadlist;
             if ( $threadcount < $topics ) { $topics = $threadcount; }
             @threadlist = @threadlist[ 0 .. $topics - 1 ];
         }
     }

     for my $i ( 0 .. ( @threadlist - 1 ) ) { 

and replace with

        }
     }

     for my $i ( 0 .. $#threadlist ) {
         if ( $i == ($topics - 1 ) ) { last;}
  

The RSS feed for Category and for the whole forums also doesn't show the subboards.  So that's on the bug fix list.

Found another bug 
New zip:

AACK!!

Your RSS feed here is working fine for me, including the listing of the sub board test.

Only a small thing. Thx Dandello. In germany we drink a beer at this time or two or .......
