The issue is that when I do try and assign a different Joomla Navigation Menu to as part of a custom set of parameters for a specific MenuItem ID, the override .ini file is created - but it doesn't seem to stop the default Joomla Navigation Menu showing up..... This is a show-stopper problem for me as a newcomer to the world of Rockettheme - Hoping it's something that has a solution!
Could a Mod Squader move it? (Unless it's ok where it is!)
