Not able to access "Updates" page logged in as admin user I am running a site on Acquia's dev cloud, using Acquia's Dev Desktop and sometime in the last few months something has changed to prevent access to the Update tab inside admin/modules/update. I'm logged in as the drupal admin, but when i try to access that page i get:


  You are not authorized to access this page.


Also on that page, cron had stopped running regularly. When I tried running manually, it would give me the same error
What worked for me was rebuilding permissions under "/admin/reports/status/rebuild" (Make sure to take a db backup).

Right after rebuilding, I saw all the available updates. 

Thought this might be of help to someone.
