Hi - I see it now. I checked HTML output and I see that the plugin uses JavaScript there. So option for "Ignoring URL" will not work here. Please contact plugin owner and ask him how the script recognizes URL which is send to Facebook (I assume that page URL is send as id of the page) and what to do in case of such communicate and what does it mean. We do not know details about how the plugin works. Maybe it is known issue for the plugin. We checked this error message in Google and there is lot of results for this. So it is issue which is common. Please check there and of course ask plugin author. As I see on your HTML output vBET do not change script content (scripts are not translated in vBET - cannot be).
