After upgrading from Drupal 6 to Drupal 7 successfully, the admin menu links are disappeared.

enter image description here

I have carefully followed the steps to upgrade it successfully. But after upgrade, I changed the administration theme to Seven and everything was working but the administration menu. What could be the problem?

Update: Management Menu snapshot

enter image description here

I tried to see if the problem is with Menu, so I installed Admin menu but after that admin menu appearing. Only problem is with Drupal7 default toolbar. What am I missing? enter image description here

  • Check what's in your "Management" menu at: /admin/structure/menu/manage/management This should be what the Admin menu uses. (+ "Navigation" menu for "Add Content" links)

  • Thanks. I also suspected the same and found Management menu looks fine.. Of course I have to reorder it after upgrade. But still nothing.

Can't tell you why, but can tell you how I fixed it last time when it happened to me:

  1. Disable Admin Menu
  2. Uninstall it if possible
  3. Delete it's files and directory
  4. Download and unpack fresh copy
  5. Clear all caches (Drupal and browser)
  6. Enable Admin menu

Worked for me, when menu disappeared during 6.x -> 6.x upgrade, when everything else failed to bring it back.

If the problem is only with core toolbar module, and not Admin Menu module, you have 2 options, really:

  1. Try steps above, just for Toolbar. You can download core archive and then just extract toolbar's directory. Admin menu and toolbar are build in similar fashion, and purging all module's data is a pretty solid method anyway, so it still can work.
  2. Give up on toolbar, and use 3rd party module instead.

    Turning off the client-side caching option often helps too

    @Clive well, back then it didn't, and when we repeated the process (it was on dev machine) it wasn't needed if steps above was applied, and that's why it is not in my answer. But good to know, thanks.

  • @pown did you try the steps above, and commenting they don't work? Or you didn't even try, because you think it cannot work?

  • @Mołot: there is no admin menu used in drupal6, in drupal 7 administration menu comes in core(toolbar module) which is coming but not listing menu's, thats the problem.
