I've successfully set-up DL 4.1 with Facebook Connect but both Twitter and Linkedin throw the same error:
"Invalid postback or callback argument. Event validation is enabled using
in configuration or <%@ Page EnableEventValidation="true" %> in a page."
Changing the EnableEventValidation in the webconfig does not resolve the issue, nor do I believe this would be the best path.
I see both of these options are functioning here on the Data Springs site so it should work...
Does anyone have any ideas or suggestions?
DL 4.1 is running on DNN 6.1
Thanks in advance for your assistance!
