 * Hi,
    this plugin causes 404 error (“SORRY, NO POSTS FOUND”) on some category 
   pages, other category pages works well. After deactivation of plugin everything
   is OK. Please fix it. Thanks, Jiri

 * I realize that this is caused by interaction with WP No Tag Base plugin (and 
   maybe other plugins which do the same like your plugin with tags).
 * If you have tag with url /something/ and category with url /something/ it displays
   only one of it.
 * The same is when you have post with url /something/ and category with url /something/–
   it displays only one of it.
 * Please can you add some mechanism which will test if url of category is used 
   somewhere else (tags, posts, pages…) and popups warning?
 * Thanks,
    Jiri

 * Thanks for providing this information. It’s an unexpected incompatibility, but
   unfortunately sometimes plugins conflict with each other. I’ll make note of this
   for a future update, but I don’t have a schedule set so I wouldn’t advise waiting
   for a fix in immediate future.
