OG:Image issue

When sharing my post on facebook, I get an Error 403: Access Denied. Here is the history of my situation.

I have Fat Panda comments on posts setup and it worked great. I installed WP Facebook Open Graph Protocol so I could select the proper image and it worked, but the two plugins caused conflict. So I deactivated and deleted Open Graph Protocol. Now, I cannot share my posts without the error.

I debugged with FB and it shows first showed Multiple OG:URL values. But now it just shows “The ‘og:url’ property should be explicitly provided, even if a value can be inferred from other tags.” It also says other things relative to an App ID.

I’m not fully sure what all of it means, trying to make sense of it. Thx for your feedback.
