Maintenance (manage extras) not showing

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.
