Issue running application after install

[ClarkElbing]

Now that we've successfully deployed the application in our environment, we're starting to test and setup the different areas. In a preliminary test where the users is asked to Introduce themselves we do get a pop up window, however the window is blank!

See attached. What are doing wrong? We've double checked all the configurations in the app to make sure they're pointing to the correct places.
Do you offer paid support? We'd be happy to pay to get this up and running.

Thanks
Brendan
