Hi there,
Thanks for try to help. I have tested both the cookies issue and the admin in: Microsoft Edge, Opera, Microsoft Chromium Edge, Google Chrome and Internet Explorer and they both only work in Internet Explorer.
Interestigly, when I click View Source I get all the code then it gets to this:

and then just stops and doesn't load the rest of the page, as in there is no </body> or </html>.
