This is not a new issue, i found that it was supposed to be fixed in 7.2.1, but alas it is not.
Here is the scenario: The ballotsopen page is for registered users only. When a user clicks a link "like Link A" from an email we sent him, the 2nd parameter is stripped from the
returnURL. However LINK B works.
I have Firebug and it showed DNN doing 2 redirects:
1 to go to the login page
2nd one to redirects to https login page, since we enforce SSL on pages. and the resulting URL looks like this:
but in firebug it shows only a single parameter comming back for the redirect to https.
It does this on our live site @ version 7.1.2. and our dev site @ version 7.3.1
