Issues with metatag module - <title> different from page title

[John.K]

CiviCRM and Drupal's metatag module do not play nicely together at the moment.

The issue is that page title tags are cached in metatag, so the <title> element on a page will not match the actual page's title in cases where the URL is the same, but the query string is different. So this will happen for:

CiviCRM Events:
civicrm/event/info?reset=1&id=1
civicrm/event/info?reset=1&id=2

I've reopened an issue in the Drupal issue queue and hopefully we'll be able to fix the compatibility within Metatag, since it isn't something we can fix within CiviCRM:

Just posting this forum thread so that people can quickly spot the cause of this problem rather than trawling around looking for it.

A temporary solution is just to leave the 'Page title' pattern for the 'Global' metatag settings empty. It will then default to the Drupal default without caching which works.
