PHP Fatal error: Call to undefined function feeds_importer_load_all() in feeds_tamper/feeds_tamper.module on line 107

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

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 

This has been a while, I think it's probably worked out.

The weird thing is that Feeds also calls feeds_importer_load_all() from hook_permission() but wasn't throwing this error.

If anyone is still seeing this, feel free to re-open.

Using the latest dev of the feeds module and the feeds_tamper module, I'm still getting the error.

drush @[website] rr
The registry has been rebuilt via registry_rebuild (A). [success]

Can you confirm that the feeds module exists? And the version.

Yes the module exists. I've completely removed the two modules, feeds and feeds_tamper and re-downloaded them. To no avail.
UID1 is getting a WSOD on login and on cache clear on any other operation through drush, the above mentioned error appears.

@AlfTheCat, can you jump on IRC? It would be awesome if I could debug this with you.

If not, there's an obvious patch, but it's icky.

I get this error without feeds tamper. I don't have tamper module enabled or downloaded.
enabling feeds with drush throws error.
feeds (7.x-2.0-alpha8)

# drush en feeds_ui -y

@twistor
Sorry for the extremely late reply and your kind offer to help. I strongly suspect it's something with my setup somehow, before taking up any of your time I'll free up some of mine and check if perhaps during updating feeds and applying the various patches required, files went missing or files from previous versions left over that are causing trouble.
So far disabling feeds_tamper got rid of the problem but again, I suspect it's feeds rather that feeds_tamper. It would be awesome of some of the patches there got committed because right now, for instance, I'm having to sacrifice automatic fetching of CSV files in order to get taxonomy inheritance working. Both patches target the same file. That's outside of our influence but my feeling is it's at the root of this problem.
Thanks again and will keep this issue updated if I find something.

I've added a hack that should fix the error.

Calling this fixed since I can't reproduce it.
