Graham Thezatls It is causing the file to have a strange mime type of 'text/x-tex' I have tried a couple of things but I am unable to get it to convert to text/html I personally cannot do anything about it so I will post a message to the other staff and see if there is a solution
as it is a bit late in the day where our staff is based I cannot get a response today so I will get back to you some time tomorrow
you should also note that according to the mathjax.org site the cloudflare cdn for mathjax was closed down on 30th april 2017
