Log in problems with GoDaddy WebMail
I have used GoDaddy WebMail for years without problems. Lately, on an iMac running OS 10.10.2, when I go to the log in page, enter my user name and password, and click "Log In," my mail screen will open. However, when I try to open a particular e-mail, or click on any other tab, I get kicked back to the log in page; the message appears that my session has expired, and I must log in again. In the middle of all of this, and without doing anything different in trying to log in, I could read my e-mail; however, my next attempt resulted in the old problem reappearing. I don't have this problem with 2 other iMacs in the house, or with my PowerBook Pro, or with my e-mail account with my cable provider.
I have called GoDaddy tech support twice. They suggested clearing the log in list, and clearing history. Didn't help. I ran the Apple disk utility, with zero results. I rebuilt all permissions, also with zero results. I ran Avira virus software--nothing found. Switching from Safari to FireFox didn't help. Before this issue began with WebMail, I was using Apple Mail, but had trouble with it too, mainly not sending e-mail, despite confirmed correct settings and ports.
Help!! TIA for any suggestions.
