I still have Movabletype 2.64 and been blogging for years with the same login. I logged in yesterday and all of a sudden it said Invalid Login. I clicked the Recover Password link, entered my username and it said User Doesn't Exist. I haven't done or changed anything to my MT files so I don't know why this is happening.
24 hours later, I can't even get to my mt.cgi file to access my MT control panel. I'm getting a 403 Forbidden error even though I never touched the permissions settings: all boxes checked except for Execute for Group and Other.
I've posted on the MT forum but there has been no response. I'm hoping that fellow Dreamhost/MT users can help me.
