When I perform a filter, my page goes to the search page with nothing on it. Thinking it might be related to permalinks (we’re simply using the post-name option or %/postname%/), I tried updating permalinks, but then I get the following error:
Warning: Invalid argument supplied for foreach() in /home/epicmoms/public_html/wp-content/plugins/cat-tag-filter-widget/cat-tag-filter.php on line 454
1) What’s the cause of the error?
2) Do I need something specific in my search template to make the results work?
