I got an error „System.InvalidOperationException” in System.Xml.dll There is an error in XML file (1, 1921).
I have absolutely no idea what to do with that.
It's connected with another error
"Cannot assign object of type System.Xml.XmlNode to SenditApi.returnStructSPUserLogin" <- this one is about login in to Sendit API which is a sandbox for a delivery company.
Any suggestions? :(
