When I go into maintenance and then go in to manage extra…at the top of the screen all i see is manage extras in white. Below there should have all the add ons to install or uninstall but nothing at all shows. I tried restarting but it does not work. So i just kept restarting over and over again into something show and it finally appeared. Is this a known issue…everything is update
It sounds like it may be related to some kind of network issue.
A bug report may help in tracking down what’s going on.
