[xwiki-users] XEM throwing 403 Forbidden for "/xwiki/bin" URLs

I have an XEM 2.1.1 installation with two XE instances. Whenever I log into either wiki instances and edit a page, I receive 403 forbidden for any URL with "/xwiki/bin". Below are some of the URLs requested but fobidden. /xwiki/bin/skin/resources/js/xwiki/widgets/modalPopup.css /xwiki/bin/skin/resources/js/xwiki/widgets/jumpToPage.css /xwiki/bin/skin/resources/uicomponents/widgets/confirmationBox.css /xwiki/bin/skin/resources/uicomponents/widgets/notification.css /xwiki/bin/skin/resources/js/xwiki/actionbuttons/actionButtons.js This only occurs when the user account is created/registered in one of the wiki instances. The user account used to administer the XEM instance is not forbidden. I assume it has to do with the rights. Thank you in advance and please let me know if you need any more information. Jared
