Hi Paul,
Thanks for your help! I actually finally figured out the problem. I hope this is a lesson for all future WordPress users, as it was a lesson for me: keep your WordPress AND pluggins up to date. As I am sure you experienced users undoubtedly already know, the pluggins are sometimes not compatible with the latest WordPress updates; in my case, I was unable to edit the page because of pluggin incompatibility.
Thanks again everyone. Happy editing.
