Error Wrong "u" parameter format

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: https://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.
