I'm trying to get some extensions enabled on a Joomla 3.6.2 CiviCRM 4.7.11 installation. For some reason the "Manage Extensions" option is missing from the Admin menu. I was able to get to the necessary page by logging into the demo and grabbing the URL for the extensions area, but how do I get it added to the Admin menu? The demo is running Civi 4.6.18, but I wouldn't think this option has been removed in 4.7. Screenshot below:
To fix missing menu items you can select Admininister -> Customize Data and Screens -> Navigation Menu (or if that menu item is missing(!) go to a civi page and change the url in your browser to end with
civicrm/admin/menu?reset=1). You can then add the missing items if you know their url and title.
