Our site has ja_portfolio on it and return URLs do not work correctly in Chrome. Steps to reproduce:
1. Go to this page in Chrome:
http://developer.connectwise.com/index.php?option=com_content&view=article&id=76&Itemid=108
2. Log in
You should now be on a page that has a return variable and says ‘you are currently logged into the Private area of this site’. If you try to go to the page again (Get Building->Installation), the same thing will occur. If you clear your cache in Chrome, everything should work correctly. I recreated this on a different article by following the same procedure. This only happens when you try to go to the page before logging in.
