Hi mestoof, I hope you are doing well. Thank you for posting in the GoDaddy community. Often issues like this are caused either by browser caching or a conflict with a browser plugin/extension. I'd suggest first clearing your browser's cache and cookies. If that doesn't help, then try using a cacheless browsing window (FireFox private window, Chrome incognito, etc.), then an entirely different browser. If that also doesn't work, I'd recommend contacting with GoDaddy team for assistance. And tell them about the login problem.
