ver 2.1.4 cannot create new pages under content


still using 2.1.4 and itching to go to ver 3 however in the meantime i cannot seem to create new pages under the content tab. i can start the page and then after i put all the information in and try to save it wont let me.

the save and save and close buttons seem like they are not working, i have tried this on numerous browsers and its all the same reult. i tried clearing cache and template cache but that doesnt seem to help either.

im at my wits end, can someone please help ?

many thanks
