I am using my own template with a custom page. The custom page displays data from an other database by variables. I use add_rewrite_rule and add_rewrite_tag (functions.php) to make the variables look nice in the urls when displaying the custom page. When I activate this plugin the NICE urls don't work (404) in the custom page. Does this plugin affect to the add_rewrite rule?
Btw, this is a nice plugin.
