{maketoc} results in empty page
Hi,
I updated my Tiki installatiopn from 4 to 5.1 today. After this (inclusive UTF8 translation) I always get an empty page, when I try to view a page with a table of content ({maketoc}).
After deleting the {maketoc} in the database, I can view the page. When I edit the page and reinsert {maketoc} I get an blank page again.
In the http access log I get an error 500, but nothing else.
Does anybody know, what to do?
Thx!
Tobias
