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.


v1.1 worked but upgraded to DNN 6.2.4 and had issues with profile. Upgraded to v1.3. As soon as you add a new page, you get above error with an ugly black stripe on web page saying Will.S .... End of Log.
Clearing cache, etc. nothing helps. Tried v1.2 same problem.
Event Viewer shows error:
InnerException: Object reference not set to an instance of an object.
FileLineNumber: 0
FileColumnNumber: 0
Method: WillStrohl.Modules.OpenGraph.OpenGraphStream.Write
Message: System.NullReferenceException: Object reference not set to an instance of an object. at WillStrohl.Modules.OpenGraph.OpenGraphWriter.OpenGraphStream.Write(Byte[] buffer, Int32 offset, Int32 count)
Not sure what this means, it actually writes to server, config file changes or creates new one.
The pages from v1.1 did not have big ugly black stripe, only newly added pages. I did not have debug turned on.
Uninstalled module to fix error.
