I am new to Joomla and have 2.5 with the T3 Ja framework and the most recent Purity template. I had also tried another template that had K2 stuff on it but I am now trying to simplify and just use the Purity template until I get my sea legs. I uninstalled all the K2 components and plugins, and deleted the associated menu item, but the K2 subMenu still shows up on the Home page menu.
I also read on OSTraining about using OSContent to delete sample data and menu links for another subMenu: "Portfolio". I checked the box to delete content and menulinks. The content was successfully deleted, but the old "Portfolio" submenu on the home menu still shows on the home page. I went in to the Menu manager and explicitly "unpublished" the "Portfolio" submenu, refreshed my browser. The the Menu item is still there on the Home page. Of course, if I click on it, I get a 404 screen. Yet, on the Joomla Pages, both the K2 and the Portfolio submenus are gone (correctly).
The site is not yet publicly available, but I have attached screen shots. I have been going through the OS Training modules and have not found examples that hint at what I am missing. Help or direction would be much appreciated.
