If your Google Map is not showing up on your Event Details page, one reason may be that your theme does not have a call to wp_footer().

Timely’s Calendar places some JavaScript in the footer that the Google Map requires to display.

One way to check to see if your theme has the call for wp_footer is to go to Themes > Editor and open footer.php. At the bottom there should be code that says <?php wp_footer(); ?>

This example is from the TwentyEleven theme from WordPress.

If your theme does not have this file, please contact your theme developer and ask them how to include it.
