We've just been made aware that some pages, when accessed via a "Warm Transfer" (this is PTC terminology for a better log-in page with some info about the tool you will use) are returning a 404 error after successful authentication. You'll notice that the URL contains an additional comma and some duplicate text.
We plan to push a fix for this on Thursday Feb 24th.
In the meantime, if you experience a 404 error, please remove the comma and all the text after it, as highlighted in the image below to access any impacted pages.
Sorry for any inconvenience caused.
