I tried your file on a test site rob and got an "out of memory" error... odd.
Anyways, just looking at your code, you have 2 sub page bottoms in there, yes, the are a little different in capitalization, but you also have 2
my $Bottom = qq~
in there, one from forum_summary and one from daily_topics... has to be erroring there... I don't see how your site is functioning with them like that...
