After installing iManager 2.7.7 patch7.
Not able to save the changes, after hitting the save button its rotating and logout automatically.

And another issue while trying to install plugins from Configure-->Plugin Installation --> Available plugins.
As soon as i hit install, its showing plugin installed but not able to view in Roles and Tasks.

eDirectory : 8.8.8 patch7
iManager : 2.7.7 patch7

Thanks in Advance,
