   Hello,

   I've been using the following code in a sidebar without any problems;

   <?php if (is_front_page() || !is_single() || is_category()) :
   $this_category = get_category($cat);
   echo"<li><h3>Sub Categories</h3>";
   echo"<ul>";
   wp_list_categories('orderby=order&amp;show_count=1&amp;depth=1&amp;title_li=&amp;use_desc_for_title=1&amp;child_of='.$this_category2->cat_ID);
   echo"</ul></li>";
   endif; ?>

   Works perfectly thanks to the advice on the forums.

   However if I move the code to a Widget which has PHP parsing enabled (have tried different plugins for this) everything works except get_category($cat) which does not return the current category ID, just null ?

   Any ideas how to get this working in a widget ?

   OK, I initially thought that this was a widget problem but it turns out to be a problem with one particular site installation.

   No matter whether I use the above code get_category($cat) it keeps returning null, where as the other sites are fine.

   Can anybody advise why this would happen - is it a themes problem ?

   Have alerady replace all the wordpress files with a fresh download upgrade copy so it has to be a theme, settings and plugin problem.

   turns out that it was a wordpress issue but I had also made some change to the code above will testing and did not revert it back after reuploading the wordpress files

   everything is working just fine now!
