Even though I change the home page back to UK, the Ukraine home page cookie gets set somewhere and isn't modified or deleted.
It usually happens after I've gone to look at the Ts&Cs of a special offer.
When it is set to Ukraine then I get similar errors to those you are experiencing when I'm logged in to my BAEC account.
Just a thought.
