wow so you're telling me your template doesn't work with Joomla's system cache?
I have reenable the system cache because it's just downright silly for your template not to work with it. So if it doesn't, then it's a bug with your template.
Regardless, you say it was a simple cache issue, but did you even look at the menus? I know you didn't because you would notice that the Mobile menu, the desktop menu, Joomla Menu Items, and the template menu builder do not match.
