category name display in full

Hello,
On http://www.software.web.tr site, the categories only diplayed as 9 fisrt category in the database… Although in reality there are over40 category there…
The problem is not related to templates used since I used over a dozen templates. but I couldnt succeded to show all categories there…
The cod to list categories there is (for this template):

<ul class=”list-cat”>
<?php wp_list_cats(‘sort_column=name&optioncount=1&hierarchical=0’); ?>

I also used following code in another template…

<?php wp_list_cats(‘sort_column=name’); ?>

What could be the reason… as you clearly see on the site when you click a program or category name of a program reviewed there, everything works perfect… but I can’t list the existance categories anyway…
