Security issue accessing FXpansion website

[FretBuzzUK]

I have been using the FXpansion website quite a bit recently but last night I suddenly find I cannot, I just get 'Secure Connection failed' with 'Error code: SSL_ERROR_BAD_MAC_READ'. Sometimes I manage to get on to the home page but then when I try and navigate elsewhere I have the same problem, I cant even get to the support page to report the problem. Has anyone else had this problem or know how to work around it. This happens on Firefox and Chrome with Edge I just a blank page.
