Hi esmi,
Thanks a million! I wasn’t expecting a response so quickly.
I did as you said and deactivated all of my plugins and then reactivated them one at a time. It turned out that the culprit was my “FD Feedburner Plugin”.
I uninstalled it, reinstalled it and then reactivated it. Everything is back to normal.
Thanks again. I was pulling my hair out in frustration.
