This is an error from feeds_tamper module right? http://drupal.org/project/feeds_tamper

Well, not your issue anyways. I should have picked that out. Thanks @dgtlmoon

This definitely don't normally happen. Could you be missing the Feeds module or something?

I have this error as well. This error would occur repeatedly when my i would flush the drupal cache with drush. It would provide the following error:

PHP Fatal error:  Call to undefined function feeds_importer_load_all() in /home/ubuntu/site/stage/sites/all/modules/feeds_tamper/feeds_tamper.module on line 107

I think i may have fixed it. I had to rebuild the my database registry with the registry rebuild module.

performing a drush rr provides the following output:

Manually deleted 1 stale file from the registry.                       [success]
A file has been declared in a module's .info, but could not be found.  [warning]
This is probably indicative of a bug. The missing file is
sites/all/modules/feeds/feeds_ui/feeds_ui.test.
The registry has been rebuilt.                                         [success]
'drush' cache was cleared
