I logged in as a super user, went to the admin panel, and then to Agents tab, added an agent and setup his username and password.
But when I tried to login with that username and password, I get access denied.
I'm pretty sure that I've logged in the correct username and password that I set when I created the agent account because I can see it on the header being returned on the developers tool.
I can login though if I sign up, and then login not as an agent though.
