ah. those super-fast admins, that can't wait for couple of minutes to update a cache.

there is a notice at the top of the page: Note: After saving, you may have to bypass your browser's cache to see the changes.

Chrome - Windows: Hold the Ctrl key and press the F5 key. OS X: Hold both the ⌘ Cmd and ⇧ Shift keys and press the R key. Safari - Hold down the ⇧ Shift key and click the Reload toolbar button. Firefox - Windows: Hold the Ctrl key, and press F5. OS X: Hold the ⌘ Cmd and ⇧ Shift keys, and then press R. Internet Explorer - Hold the Ctrl key, and press F5 (or click the Refresh button). ensure that changes in the sitewide css were alive for at least 15 minutes (the cache have to be purged, of course) before considering them as "not working".

moreover, we can't say what is going wrong if edit was rolled back. so, before asking for help, ensure that all changes in the css are exists in the current version.
