Debugging mode:

When debugging mode is ON, FeedWordPress displays many diagnostic error messages, warnings, and notices that are ordinarily suppressed, and turns off all caching of feeds. Use with caution: this setting is useful for testing but absolutely inappropriate for a production server.
Diagnostics output:
  • /> Log in PHP error logs
  • /> Display in WordPress admin footer
  • /> Echo in web browser as they are issued
  • /> Echo to output when they are issued during an update cron job
  • /> Send a daily email digest to:
array( 'updated_feeds' => 'as each feed checked for updates', 'updated_feeds:errors:persistent' => 'when attempts to update a feed have resulted in errors
