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.

Metatag 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 :-)

I should have included the whole error message:

PHP Fatal error: Call to undefined function entity_language() in /mysite/public_html/sites/all/modules/metatag/metatag.module on line 1621
