This was an issue with cached functions from an extension that had been removed. Manually clearing the cache fixed the issue.

Manually clear the cache using one of the following methods:

  • Use standard method Mage::app()->cleanCache() or Mage::app()->getCacheInstance()->flush();
  • Use n98-magerun to clear the cache from the shell. (https://github.com/netz98/n98-magerun)
  • Manually delete the var/cache directory (if file cache)
  • Clear relevant db/redis/memcache cache

Additionally sometimes apc or opcode cache can cause issues, and restarting php may be required in those cases.
