Hi everyone

I performed a drupal upgrade from 6.x to 7.34

Everything went well, but once i'm logged as administrator, I cannot see the Modules, Themes and Content sections in my admin panel.
If i try to reach them manually with the url admin/modules. I got a Access Denied page.

I already tried to create a new admin account, rebuild roles, clear caches, etc... but nothing fixes my problem.

Can anyone help me with that ?

Thanks
