Dear all,
I have added 'Facebook Authentication' (API 2.5) and Google Auth on my DNN 7.4.2 portal. Facebook gives me the error below. Any ideas what might be wrong?
On the page I see the following:
A critical error has occurred. Please check the Event Viewer for further details.
In the EventLog the error below:
