Not allowed to submit translations in this language.

I have the same issue here with l.d.o. Don't know if this is the right place for reporting or it should be on the l10n_server or d.o infrastructure project issue queues.

The offending line seems to be

  // Check if the user has permission to submit strings in this language.
  if (!user_access('submit suggestions', $account)) {
    //watchdog('l10n_community', 'Not allowed to submit translations in this language remotely.', NULL, WATCHDOG_WARNING);
    return array('status' => FALSE, 'reason' => 'Not allowed to submit translations in this language.');                                                                
  }

on l10n_remote.module in l10n_server module, but I setup my key following the instructions and I have a trusted role on l.d.o for the Spanish language.

Other Spanish translations contributor (@mariogalan) mailed me about having the same problem.

Was fixed by #1673074: localize.drupal.org "Not allowed to submit translations in this language."
