Trying to connect to a WMPS service source and getting error "An error occurred while getting MapPublisher Applications"
If the WebMap Configuration Test is fine but the WMPS is not working with the error "An error occurred while getting MapPublisher Applications", then you may want to try creating a demo WMS to see if that works.
