   I have Level2Categories 2 working in 2.8.6. Here are the changes I made.

   In function l2c_admin, change 'add_management_page' to 'add_opeions_page':
   

   function l2c_admin() {
      if (function_exists('add_options_page')) {
         add_options_page('Levels2Categories Options', 'Levels2Categories', 8, basename(__FILE__), 'levels2categories_admin_page');
      }
   }

   In function l2c_disable_cats, insert line '$user_level = l2c_user_level()':
   

   function l2c_disable_cats(){
      global $l2c_table, $user_level;
      $query=mysql_query("SELECT * FROM $l2c_table");
      $cat_total=mysql_num_rows($query);
      if ($cat_total > 0) {
         $user_level = l2c_user_level();
         echo "<script>";
         while ($fetch=mysql_fetch_array($query)) {
            if ($user_level < $fetch['level']){
               echo "document.getElementById('category-".$fetch['cat_ID']."').style.display='none';";
               echo "if(document.getElementById('popular-category-".$fetch['cat_ID']."')) document.getElementById('popular-category-".$fetch['cat_ID']."').style.display='none';";
            }
         }
         echo "</script>";
      }
   }

   Add new function l2c_user_level:
   

   function l2c_user_level () {
      for ( $i=10; $i>0; --$i) {
         if (current_user_can('level_' . $i)) return $i;
      }
      return 0;
   }

   Interesting - I applied this fix to my install (WP 2.9.2), and it rectified a rather strange issue. The plug-in had been working as designed, but then stopped doing so; the only variable (other than demonstrating to a customer, which always brings out the worst in any system) was that I had experimented with some other (unrelated) plugins in the meantime (but had de-activated and deleted all of them).

   Thanks for contributing the fix!
