Just to confirm, does that mean you also cleared cookies and not just your browsing history? Specifically, the cit_session cookie for cit.cohtitan.com and cohtitan.com must be deleted if present.Could please you try using Incognito mode and see if it lets you log in that way?
The changes are now live. You may need to clear your cookies before you can successfully log in, though. Sorry for the hassle!
