404 error when adding user to event in front-end

Hi guys,

Since a few days I get a 404 error in the front end when I want to add a user to an event.

Php = 7.4
Joomla = 3.10.11
EB = auto update \ but actually shown „update status unknown“

What can I do to narrow down the error?

 Thank you

There could be something special on your site causing this error. Please submit a support ticket sending us super admin account of your site and link to the page which I can see the error. I will check to see why the issue happens and get it sorted
