I am not a sharepoint expert but I am just starting to learn how to mange/adminiter sharepoint.
I did something by mistake yesterday and DELETED a webpart. (Clicked on edit page and clicked on the X) the webpart was GONE.
Clicked on Add A web part
Added the name of the webpart
it is now addedd but in a different view (List view) and i dont have the UPLOAD documents button on the top or any other buttons that used to show
(New, Action, Settings) and so on/
