Hi All,
I have recently deployed a new version of the D365 Marketing Event Page. Unfortunately for me, our external vendor has apparently set up the "test" site incorrectly, and the deployment has broken both pages despite being pointed to the correct website binding.
We're now in a total mess as the Event Page no longer loads and displays a 404. It appears that the "test" event site's URL is being inserted into the real event site's URL - it gives the below error:

Any help or advice you can give is very much appreciated. Microsoft has no idea and have sent this to "the developers".
