Running upgrade CiviCRM 4.7.8 to 4.7.13, on Drupal 7, I have a white screen with just "[]" message and "Retry" and "Skip" buttons, and js error : CRM.$ is not a function. Tried to change the theme : no effect. js and css files are not compressed.

Do you have any idea ?

  • Have you run upgrade.php? – naomi Nov 9 '16 at 17:44
  • Also have you cleared the browser cache? – naomi Nov 9 '16 at 17:44
  • When I run upgrade.php I have this error (after confirmation). And I have cleared the browser cache. – acceleroweb Nov 10 '16 at 15:11

I recommend doing the upgrade via drush if you are having trouble doing it in your browser.
