Click to add new – goes to frontend home page

Hi,

I have used your plugin a lot, but since I last updated when I go to add a new post the new post pages does not appear, infact I get redirect to the frontend homepage.
Even when I click to edit past posts, I get redirected to the frontend homepage.

Has anyone else had this problem?

Thanks,
