Can't Update Contrib Modules via Admin UI 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&amp;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.
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
