[xwiki-users] After upgrading from 1.4, strange errors everywhere

After upgrading from XWiki 1.4(ish) to 2.0.1 I see stuff like the following appearing on all pages in the wiki: $xwiki.jsfx.use('js/scriptaculous/effects.js', true) $xwiki.jsfx.use('js/xwiki/widgets/modalPopup.js', true) $xwiki.ssfx.use('js/xwiki/widgets/modalPopup.css', true) $xwiki.jsfx.use('js/xwiki/widgets/jumpToPage.js', true) $xwiki.ssfx.use('js/xwiki/widgets/jumpToPage.css', true) $xwiki.jsfx.use('uicomponents/widgets/confirmationBox.js', true) $xwiki.ssfx.use('uicomponents/widgets/confirmationBox.css', true) $xwiki.jsfx.use('uicomponents/widgets/confirmedAjaxRequest.js', true) $xwiki.jsfx.use('uicomponents/widgets/notification.js', true) $xwiki.ssfx.use('uicomponents/widgets/notification.css', true) $xwiki.ssfx.use('resources/uicomponents/viewers/tags.css', true) $xwiki.jsfx.use('resources/uicomponents/viewers/tags.js', true) $xwiki.jsfx.use('uicomponents/viewers/comments.js', {'forceSkinAction': true, 'language': ${context.language}}) $xwiki.ssfx.use('uicomponents/viewers/comments.css', true) $xwiki.jsfx.use('js/xwiki/viewers/attachments.js', {'forceSkinAction': true, 'language': ${context.language}}) $xwiki.ssfx.use('js/xwiki/viewers/attachments.css', true) Some of it is at the tops of pages and some at the bottoms. I'm assuming I did something terribly wrong during installation of 2 and subsequent import of the new stuff from the xwiki-enterprise-wiki-2.0.1.xar. Having done it several times, however, I'm a bit stuck pinpointing what precisely it was that I did incorrectly. If I import any of the pages I excluded initially, like the XWiki.XWikiPreferences, it more-or-less destroys my wiki. Additionally, the users and groups in the Administration pages don't show up correctly; a barbershop "loading" pole spins forever. If there are other problems I've been too preoccupied with the former issues to notice them yet. I suspect they're all related to the same thing, whatever it was, that I messed up. Any suggestions would be much appreciated! Thanks, - AW
