One of my applications that has worked until recently will not open. When accessing the application, it returns an error message indicating that an error has occurred and is unable to create the map. I tested to make sure there was nothing wrong with the web map, but found no problem here as it (and the data layer) loaded fine. When trying to access the application however, even by selecting the option to configure the application, I continue to receive this error message.
Does anyone have recommendations for resolving this issue?
