Ive been using a WIKI in my class for my pupils. When I go and update a page, after all the pupils have gone home for they day!!, it only allows my to update it once before it says
Sorry, while you edited this page someone else did already save a changed version. Please go back to the previous screen and copy your changes to your computers clipboard to insert it again after you reload the edit screen.
Is there a setting that can change this.
