I'm having a problem with a new Drupal site I'm working on. I installed Drupal 7.36 and am able to install contributed modules via the admin UI and Drush. However, I cannot update any contributed modules via the admin UI. I can update via Drush however.
The error I'm getting is as follows.
An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /wcbvi/batch?id=9&op=do StatusText: Internal Server Error ResponseText:
I'm running Ubuntu Server 14.04.2 (32-bit) in VirtualBox with Apache 2.4.7 and PHP 5.5.9. I've also installed Curl, Composer, and Drush.
