If I replace this:<\/p>\n

wp_list_cats(‘optioncount=1&hierarchical=1’);<\/p>\n

with this:<\/p>\n

if (function_exists(‘wp_dtree_get_categories’))
\n{
\n wp_dtree_get_categories();
\n}
\nelse
\n{
\n wp_list_cats(‘optioncount=1&hierarchical=1’);
\n}<\/p>\n

etc. in my sidebar.php, as per your readme file, I get a validation error. The site is http:\/\/www.ostrogothia.com . The validator link is in the page footer. If I disable the plugin, the pages validate ok.<\/p>\n

I’m running version 3.4 of WP-dTree and 2.6 of WP.<\/p>\n

I really like the functionality as I plan to have plenty of pages in a hierarchy on one of my sites.<\/p>\n

Thanks,
