CiviCRM Community Forums (archive)

My civicrm system is hosted on linode using ubuntu.

During development I accidently attached to my production db and deleted some stuff .... arg.

So I decieded to restore from the latest VM snapshot.
This all went smoothly until I attempted access civic and which point I got the following errors:

PHP Fatal error:  require_once(): Cannot redeclare class crm_core_classloader in /usr/share/drupal7/sites/all/modules/drupal/civicrm.module on line 278
PHP Fatal error:  Cannot redeclare class CRM_Core_ClassLoader in /usr/share/drupal7/sites/all/modules/civicrm/CRM/Core/ClassLoader.php on line 41

After some investigation I see that people have this error when migrating to a new system and the ip address changes. This is not the case for me as I restored from a snapshot and for all intents and purposes the system is identical.

I stuck the following at the top of the ClassLoader.php:

foreach (get_included_files() as $file) {
  echo "$file<BR>";
}

In the resulting output I noted the following two lines (complete listing at the bottom of this post).
/usr/share/drupal7/sites/all/modules/CRM/Core/ClassLoader.php
/usr/share/drupal7/sites/default/civicrm.settings.php
/usr/share/drupal7/sites/all/modules/civicrm/CRM/Core/ClassLoader.php

Note: that I seem to have two version of this file.
Once I renamed one of the ClassLoaders loaders everything started working fine.

What I don't understand is how I got two of these loaders. The only thing I can thing of is that I've just started working on a Civicrm extension and so I've added the necessary tooling to make this happen. Could this have added a second ClassLoader instance?

What is the correct method to fix this problem?

Thanks in advance,
Brett

might want to ensure you only have one copy of CiviCRM under your sites/all/modules directory

seems like there are two copies right now,

In the resulting output I noted the following two lines (complete listing at the bottom of this post).
/usr/share/drupal7/sites/all/modules/CRM/Core/ClassLoader.php
/usr/share/drupal7/sites/default/civicrm.settings.php
/usr/share/drupal7/sites/all/modules/civicrm/CRM/Core/ClassLoader.php

The first file there should not exist. The third file is correct.
