Cannot "Login As" from Nexus

When I try to login-as, I get the following error and put back to the nexus page.

  • Category `crm’ does not exist
  • Page_Container::_processPostback(): CSRF check failed. Login required.

Logout, log back in, clear cookies, none of it matters.

Hrm, rebooted and it’s working

You have a duplicate session with alternative credentials opened in a different window. Opening a separate session overwrites the client-side CSRF challenge. You can verify the correctness of this by interacting with the demo admin account in a private browsing session, which would be void of any other tabs potentially overwriting the CSRF challenge.
