Raw XML being sent to my site via JobAdder

Site URL: https://romablack.squarespace.com

Hi Guys,

I have some raw xml being sent to my domain https://romablack.com and I'm not having any job, They have shown me what XML is being sent to the site and I have a schema file also but I cannot get it to show any data.

Would I need to have the raw data sent to built in domain instead of the custom bought domain?

Is there anyone in this group familiar with XML that could maybe help me out?

TIA

Dan
