This is going to be a bit odd, but I am hoping someone might have an idea of what is going on.
Joomla 1.6.5
Gantry 3.2.7
Using the default Gantry template, RT Paradox or RT Quantiative...it does not matter. Everything looks great EXCEPT, I don't have the Fusion or Split etc options when I add or edit a menu item.
Menu is assigned properly and Fusion-Menu is turned on in the template parameters. Gantry-System is enabled and, except for this issue, everything seems to work and report just fine.
Shot in the dark here, are you using the most recent version of RokNavMenu? You might want to grab the latest version and try re-installing the bundle. Let me know if that helps.
The difficult we do immediately, the impossible takes a little longer.
