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.

    That is a generic error, can you look into your error_log or even look at "drush ws --tail" and then try UI and see what errors are generated.

No guarantee it will help, but I think it's worth trying (inspired by some of the suggestions in this comment in issue nr 1022558):

  • Increase the php memory limits by editing the following lines in the php.ini file as:

    • max_execution_time = 30 --> 60 ;
    • memory_limit = 32 --> 128, or even 256M ;
  • Add the following lines to the end of .htaccess file:

    • php_value auto_append_file none
    • php_value memory_limit 128M
  • Thanks for the suggestions. I tried all of these yet the issue was not resolved. However, I've since moved to a 64-bit Ubuntu Server and set it up seemingly in the exact same way and this issue did not reoccur, so it remains a mystery.
