Editor Contents Empty on Backend

I use this plugin frequently and have never had a problem with it until recently. I can’t recommend it enough. However, the last time I tried to use it I’ve found that all of the editors on the back end are empty for both posts and pages. The titles are still there and all other parameters and setting are there and accurate. But the big WYSIWYG editor is empty. The interesting thing is if I go to a page/post on the public side, all the content that should be there actually does show up until I visit the same page on the admin side. Then I see the empty editor box and a second visit to that same page now shows it empty. Has any ever heard of this or have any idea of what could be happening? Thanks!!
