Pretty sure its a cookie issue, can someone do as in post 8 above and confirm this fixes it?
To delete cookies in Mac Safari:
1. Go to Safari>Preferences>Privacy
2. Click on the DETAILS button and search for Sportsmaserati, sportsalfa, sportslancia, sportsferrari, sportsitalia and delete all these cookies.
3. Go to History top menu and at the bottom, CLEAR HISTORY
4. Under the deleop menu (if you have it) select empty caches or ALT + APPLE + E keys
5. go to SM and log in and check the remember me box.
Tried all that but it doesn't work.
It seems to be a conflict between SM's log-in fields and Safari's new "helper".
I cleared everything and SM acknowledges I'm a "new visitor" - I get the little message on the yellow background suggesting I read the FAQ.
But at the same time I constantly (every few seconds) get the following dialogue box, BLANK no information in the fields. It's like Safari is attempting to submit a blank username and blank password. Unsurprisingly SM rejects this.
Then when I do enter my credentials it returns it again with the username remaining but the password removed. Selecting or deselecting 'Remember this password…' makes no difference.
If I keep clicking Cancel and enter my details into SM's fields I get the following error message:-
This only happens on the home page. I can log-in, using SM's own fields, on other pages.
It seems to be a SM only problem because 10.9 and Safari 7.0.1 are working happily with all other fora.
