A escaped bug makes the #adminmenu set over all the admin content.
If you has this problem, just delete the plugin on plugins folder and and reinstall.
Advanced:
If you know how use the Firefox/Chrome inspector, in update page (/update-core.php), just select the “over all” element and “delete” in code, then update.
