mrkl

Yes you are right, that was the problem.

The form was marked as “edit profile” not for registrations.

THANK YOU so much!

Thanks again for your help. 

I checked both, the page is not restricted. 
And i switched to "use language directory" but it didn't change anything.  

So i have added the code to the function.php 
Then i have navigated to the german page 
(https://shop.wordpress-agentur-kaiserslautern.de/registrierung/)

and then clicked on the english link 
(https://shop.wordpress-agentur-kaiserslautern.de/registrieren-5/?lang=en)

Thanks for your quick reply.

I tried it all but it didn’t help. Do i need to add anything to the source code, or is it just that line?

Even when i put the shortcode on a new page it redirects to the frontpage. https://shop.wordpress-agentur-kaiserslautern.de/testing/

Thank you Joy!
I will have a closer look at the ability to flush the rewrite rules.
Maybe i try to call: flush_rewrite_rules()

i have the same problem with Raidboxes and Easy WP SMTP.
Hope there is a solution for this…
