I get the following error when I try to login: Error: 0 Invalid Controller: name='user', format=''
I use jbusiness directory and I think it is a conflict with SCLogin Enhanced Login and the component. Error is displayed when you login at the following menus (categories of jbusiness directory):
Support of jbusiness directory have checked my website and they could not find any issue with their extension.
When normal menus are active login is working fine and with default joomla login is working too: https://gesundheitsanbieter.de/anmelden
Would be great if you can find and fix the issue, thanks.
When you try to login with SCLogin on this page, does it work?
If that works, then SCLogin is working.
On the jbusiness directory pages, can you place a standard Joomla mod_login module and test if that has the same issue, on those pages? If so, then the issue is something else and not related to SCLogin.
If it the Joomla login module works, please leave it enabled and let us know what page it's on. Also, please post test (not admin) credentials that we can test authentication with.
