Hướng dẫn rebuild Drupal 7 administration menu

Sometimes it happens your Drupal 7 administration menu gets scrambled. This may be caused by some nasty modules, or like in my case it was inherited from MySQL crash in Drupal 6 version of a site.

Of course you can use Devel module which has a menu rebuild link in its block. But if you don't have Devel module installed, don't worry, it is easy and safe enough to fix menu manually in Drupal 7:

• Delete you current links via SQL DELETE FROM menu_links WHERE menu_name='management'.
• Clear all caches at Administration > Configuration > Development (or just: http://example.com/admin/config/development/performance if your menu is ruined at this point). Drush users can of curse use drush cc allor even drush cc menu

The consequences: your administration (management) menu is reset to defaults. If you had any custom links attached to it (or menus created in views, etc.), they were moved to navigation menu now.
