A critical zero day vulnerability has been discovered in the software provided by vBulletin which we use for the member forum. More information can be found in this article https://www.zdnet.com/article/anonymous-researcher-drops-vbulletin-zero-day-impacting-tens-of-thousands-of-sites/
To ensure the forum is not compromised it has been taken offline temporarily until an official security patch has been released and we are able to carry out the necessary upgrade work.
We will update members in due course. Apologies for any inconvenience; as ever do contact the membership team if you have any specific questions on [email protected]
