 * Hi Mattheus,
 * I responded to your email–there’s no need to post this twice and email twice 
   about it. In the future, one contact is enough.
 * Please post a screenshot showing where the error happens so I can understand 
   the context.
 * What version of WP are you running?
 * Have you tried running a conflict test? Here is an article about how to test 
   for theme and plugin conflicts with Business Directory, which may help pinpoint
   the issue: [http://businessdirectoryplugin.com/support-forum/faq/how-to-check-for-plugin-and-theme-conflicts-with-bd/](http://businessdirectoryplugin.com/support-forum/faq/how-to-check-for-plugin-and-theme-conflicts-with-bd/)
 * It’s possible some new plugin you recently added is doing something to the URL
   inadvertently. But without knowing more about it, I’m just guessing here.
