V-Flyer and Safari

Has anyone else had this problem - everytime I have tried to log into V-Flyer today on my Macbook with Safari I get a message in a large font which reads 'Bad Request (Request header too long)'. However if I go into Chrome on my PC I can get in fine (which is were I am now) No other website which I visit is affected only V-Flyer.
I had the same problem a few days ago and emailed Pete but he found it OK and in fact it rectified itself a short time later.
It's annoying to say the least as most of the time I use the MacBook as the PC is inconveniently situated in the house
