Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
In Drupal 7.14 after enabling metatag, I had a white screen on my non-admin pages, but not on admin pages. In the PHP Error log, there were entries saying, "Call to undefined function entity_language()" in the metatag module.

DamienMcKennaMetatag now requires Drupal core 7.15 or newer, if you check the admin/reports/status page you'll see an error message telling you to update. Please update your site :-)
