Portal 5.02, Manage Document Libraries portlet is unavailable
|
|
|
| I am going to Administration->Portal Content->Manage Document Libraries.
I get "Portlet is unavailable". and from there on it seems to be every tab is hung ..I can't access any other tabs. I have to log off close the browser and log back in.
I can't access any related document libraries too.
Please suggest.
System.out gave me the following error
