[MM3-users] Can't edit lists anymore: "Something went wrong HTTP Error 404"

When I try to edit any list at "postorius/lists/LISTNAME.SUBDOMAIN.DOMAIN.TLD/", I get this error. The lists are displayed correctly at "postorius/lists/". Selecting any of those lists leads to that error. First step of creating a new list is possible but I get the same error right after the creation of the new list.

I see a few hours later you posted again, with a different issue. Was this problem resolved?
