I upgraded my Piwik install to 1.7 this morning. And now where I was using Piwik on my site embedded through an iFrame and using single sign on, it no longer works. But it does work if I just go directly to Piwik not through an iFrame. I double checked that my config.ini.php file still had the
enable_framed_logins = 1
option enabled. Also, if I change my piwik user’s password to force an error with the single sign on, I get an “username/password” don’t match screen in the iFrame. But when I change the password back to the correct one, I just get a blank page. It’s like the single sign on worked but then nothing gets rendered afterwards. Any ideas?
