I am using Dynamic Login module since Dec. 2010 (Ver 3.5) in our internal website (DNN version 5.6). It is working well.
But suddenly in this morning, the login page shows 'Initial Setting layout page of Dynamic Login module' asking we need to set up this module instead of showing our normal login page then nobody could not login.
So I did login as administrator through another dnn default login page of our website and opened the setup page of Dynamic Login module page. But I did not do anything else.
Then suddenly our normal login page started to work again as usual.
I don't know why. So as one of possibilities, just in case, I am wondering this module is always checking the module license through online? Or is there another reason of this happening?
