When the users go to wordpress admin console and open a post that they want to insert image in, it is not working. I can see the following error in firebug
Access to restricted URI denied" code: "1012
wp-admin()
(function(){var R=/((?:\((?:\([^()]+\)|[...J,typeof K==="string"?K:K+"px")}})})();\n
wp-admin/load-scripts.php?c=1&load=jquery,utils,quicktags&ver=b64ae9a301a545332f1fcd4c6c5351b4
The weird thing is that it works fine on some of the users and some of them are having this issue.
