still the same problem with another error:
Fatal error: Allowed memory size of 52428800 bytes exhausted (tried to allocate 30720 bytes) in /home/xxxxx/public_html/includes/local_links_include.php(2594) : eval()'d code on line 14
isn't 50M really too much for an application?
thanks for the fast answer
ADD: got the point.... i have more than 1500 categories and this kills php

it worked hardly with 70M memory_limit!
just wanted to test how it looks like. it's a perfect feature for databases with less categories and looks very nice
