In admin, I click on option "Menu" and unpublish a menu item, I get the message "successfully unpublished." The little red dot appears to the left of the item title. Clicking on the menu title in the admin, it shows that it is unpublished (bar on right is red). Yet on the front end the item is still there in the drop down menu. I've even put a menu title in the trash, but it still appears on the front end. Am I missing a step?? Am on Joomla most recent version all updated. NOTE: This problem is specific to the menu! All article and module changes DO reflect on the front end. Many thanks.
You don't say if you built this site yourself, but my suspicion would be that the menu has not been created by Joomla's core menu module, but instead has been hardcoded somewhere. Have you ever made drop down menu changes via the menu manager that are reflected on the front end?
Are you able to find the menu under Extentions > Modules. If so, is it of the type "menu", and does it vanish if you unpublish the module. If so, look at the files under templates/YOURTEMPLATE/html/mod_menu to see if the layout has been overridden.
There is a chance it is also a caching thing. Updating a menu item should flush the cache, but it might be worth going to System > Clear Cache, and also giving your browser's cache a force refresh. Are other changes appearing?
Problem resolved. Our site has two parallel menus for the menu item I was wanting to unpublish: Main Menu and Global Locations. In order for the changes to reflect on the front end, the changes need to be made in both menus and I had only changed one of them. Many thanks to Richard B and Drew G for your feedback and suggestions!
