I'm on chorme, set on auto-login mode ("remeber me"). When i go on cm.org, i'm well logged in.
But when I click on a music, the AJAX call "getItem" fail and I keep having this issue in the morning :

OPTIONS http://chipmusic.org/music/ajax_get_ite … j---wreckd No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.chipmusic.org' is therefore not allowed access. jquery.js:19
XMLHttpRequest cannot load http://chipmusic.org/music/ajax_get_ite … ---wreckd. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.chipmusic.org' is therefore not allowed acces

I have to logout/login to get it to work again.

if you need some specific test, let me know.
