I have created a Enterprise Wiki site collection , then i tried to define a tem store for it, but when i go to ---> Site Settings----> Term Store Managemnt. i got the following error:-
The Managed Metadata Service or Connection is currently not available. The Application Pool or Managed Metadata Web Service may not have been started. Please Contact your Administrator.
Baring in mind that i have enabled the "Managed Metadata Web Service" service and i am the site collection administrator ?
