   I'm using the following in my query to display the child categories

   <?php
   foreach((get_the_category()) as $childcat) {
   if (cat_is_ancestor_of(1, $childcat)) {
   echo $sep,'<a href="'.get_category_link($childcat->cat_ID).'">',$childcat->cat_name,'</a>';
   $sep = ' / ';
   }}
   ?>

   So this is then displaying as follows:

   Category a / Category b / Category c

   The problem is when there's more than one post on the page the next lot show as

   / Category a / Category b / Category c

   i.e. it's just continuing to add the forward slash and not simply starting the query again.

   Basically I need it so the separator does not show at the beginning or end of the category list.

   Any help would be greatly appreciated.

   there is a comma after $sep which might break the code - should be a dot;

   try:
   

   <?php
   foreach((get_the_category()) as $childcat) {
   if (cat_is_ancestor_of(1, $childcat)) {
   echo $sep.'<a href="'.get_category_link($childcat->cat_ID).'">',$childcat->cat_name,'</a>';
   $sep = ' / ';
   }}
   ?>

   Thanks for that - I've changed the comma to a full stop but it hasn't had any effect to the original issue.

   ok, i get it ;-)

   before the foreach, you need to reset the separator to an epmty space:

   $sep = '';
