I installed Google Analytics pugin v2.3 in this PrestaShop site.
But Analytics is not tracking any sessions. I already setup the account in admin. Google Tag Assistant says that it find the GA account, but nothing is fired.
How can I fix this?
That's because plugin is missing
ga('send', 'pageview');
in it's javascript snippet.
Javascript snippet is in modules/ganalytics/ganalytics.php
You can add the command there, though you'd probably want to override module to prevent it being erased if module gets updated.
