I'm having a problem with categories. I'm using this tag <?php list_cats() ?> to invoke a list of all categories. I also tried <?php list_cats(0, 'All', 'name'); ?>. Both bring up the category list fine but when I click on any of the category links I get this error:
"Warning: Invalid argument supplied for foreach() in /home/fetal/public_html/index.php on line 100"
I'm using version RC 101 and I have SEFriendly URLs feature turned on if that is related to the error.
