Are you sure you want to do this? Please try again.

I have recently migrated my website from my computer locally and it’s now live with the help of BackupBuddy. Everything seems ok. I tried to create a new page and keep getting the message “Are you sure you want to do this? Please try again.” when I attempt to save it. The options on the right look drastically cut down to the pages that have been already published.

The only options for saving this new page are “save draft” or “send for review” I thought it may be a privilages issue but I am admin so there should be no problem there. The only plugin I have active is BackBuddy so now I am a bit stumped. Am I missing something obvious? Would appreciate some advice.
