Similar error happening to me today. Yesterday was everything fine. Today it spins forever.
When I try to login from another computer or my smartphone it works. Only from my work computer it does not log in.
What I have done sofar:
- Cleared Browser cache Cookies, History, Pictures
- Cleared the cache both from backoffice options and also ftp manually.
- Tried with IE and Firefox
I tried to read all the entries related login problem but non helps.
Any idea about this issue?
