I´m gettting thios error:
"The open graph protocol HTML mark-up cannot be loaded from cache. It is suggested that you clear cache in the control panel to fix this issue." and at the bottom of the page this message appears:

"at WillStrohl.Modules.OpenGraph.OpenGraphWriter.OpenGraphStream.Write(Byte[] buffer, Int32 offset, Int32 count)

END OF LOG"

I dnd clear the cache as HOST, and debugging is not enabled in site-level settings of the plug in. My locale is Es-es if that helps.
