# Category Link Problem

 * 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. Any ideas?
   Thanks

 * If this was an upgrade, make sure you have redone the Permalinks feature (just
   follow the same process as before, after the upgrade)

 * Thanks very much LL – after redoing the permalinks everything works great.
