"Not found" when accessing an organizations' site

[Ra Jo Ga Cha, geändert vor 6 Jahren.]

This is in 7.0 GA3, clean installation. I created an organization which creates it's own site, and I can access that site with a superuser (p.e. test) but not with a normal user that is in the organization and without any organization role. I try to go into the organization and Liferay returns this in screen:

Status
Not Found
The requested resource could not be found.

http://x.x.x.x/group/control_panel/null

The URL you're going to is not a valid URL, so the error message that you're seeing is expected. Even if an administrator goes to that URL, you'll see the same error.

It's how the error looks, but the strange thing is that I'm trying to access the site in the same way with each account:

Liferay [Site] - Go to other site - OrganizationSite

This works for Test but not for a standard user which is part of the organization

Edit: Error disappeared with 7.0 GA4.
