What to do if my user-defined ribbon does not show? (There is no error message)

For Access 2007: "Office Button" / "Access Options" / "Advanced" / "General" / "Show add-in user interface errors" needs to be checked.

For Access 2010 and Access 2013 use: "File" / "Options" / "Client Settings" / "General" / "Show add-in user interface errors"

With this option switched on all errors generated by Ribbon XML will be shown.
