   Not sure why this is occuring but the page menu disappears when I view a list of tags e.g. http://www.openeye.net/tag/analog. It only happens when the plugin is enabled.

   With Menu (plugin off)

   Without Menu (plugin on)

   Any thoughts on what could cause this?

   Hi whiteorb,

   Hmm, I've never heard of such an issue before. - Maybe there's a conflict with another plugin or your theme.

   To test please deactivate all plugins and reload your test-page with only TagPages activated. If it worked, try to activate one plugin after another and reload the page each time.

   If it didn't work, try to setup one of the default themes (TwentyTen or TwentyEleven).

   Greetz,
   Berny

   It doesn't occur with the default themes. Can you think of anything that could possibly cause this?

   So it was caused by this function

   add_filter('pre_get_posts', 'query_post_type');
   function query_post_type($query) {
     if(is_category() || is_tag()) {
       $post_type = get_query_var('post_type');
   	if($post_type)
   	    $post_type = $post_type;
   	else
   	    $post_type = array('post', 'software', 'documents', 'news', 'nav_menu_item', 'page');
       $query->set('post_type',$post_type);
   	return $query;
       }
   }

   Fortunately, I don't need it any longer. Curious though why that would happen.

   Cool. - You found the issue. :) I'm also curious, so here's an idea:

   As I also use a pre_get_posts-filter to manipulate the post_type in $wp_query, it looks to me like a race condition between the two filters.

   Your code sets the post_type to array('post', 'software', 'documents', 'news', 'nav_menu_item', 'page'); if the post_type has not been set before.

   TagPages sets the post_type to array('post', 'page') if the post_type has not been set before.

   So, if the TagPages-filter is executed before your filter, it will never reach your else-fork.

   The default $priority = 10 for all filters, so I think setting your function to a higher priority (e.g. to 9) would achieve the desired functionality.

   Ah ok, so I set the priority before the function and that seemed to resolve another issue that had come up. Very cool!
