Hi,
We use SCLogin together with JFB Connect in order to have our users logged in. But yesterday it stopped working. Actually I don't think the error is related directly to your products but I hope you will help anyway.
A month ago we swiched to https but this has not caused any problems.
If I go to our facebook developer account I have an alert related to the facebook login app which could be related since the date matches the error. Please see attachment.
If I try the suggested tool I just get the other picture attached. I cannot select versions prior to 2.3 in the first selection list.
Write back if you need any credentials in order to have a closer look.
Thanks.
Claus.
