I have WP 3.5 installed on my website (www.erudiomag.com) and I have been facing constant problems with this error- "You are not allowed to edit this post." in spite of being the admin.
My contributors are also facing the same problem.
I have searched the forums and unfortunately, could not find a n00b-friendly answer. I'd be eternally grateful if someone could help me solve this issue asap & step-by-step. :)
