Firefox anomaly logging into a site

[Chris Wilson]

I have an anomaly logging into a regular site I am a member of. It worked fine until at certain times this week.

If I try and log in to the site at:

http://www.mkivsupra.net/

with Firefox I am getting this screen:

If I use IE I access fine, and can log in. Any ideas? Other forums / sites with Firefox appear fine. I manually input the URL into both browsers. Thanks!

Just found if I drop the www. part it connects. But it's a PITA as e-mail notifications of a message reply have the www. in the link, so have to manually copy / paste then delete the www. part. Any ideas whay this has suddenly started occurring this week? My Internet connection via Zen Internet and BT and an ADSL Router from Netgear has generally been problematic of late, with LOTS of dropped connections. I *SUSPECT* my aluminium cable, out in the stocks link to the local exchange is overloaded, it plays up when the school kids are at home... Thanks.
