[Plugin: Events Manager] How can I choose which sidebar EM pages use

this link might help you out – https://www.ads-software.com/support/topic/events-manager-eventslocation-pages-cant-get-sidebar?replies=20

For single events – single-event.php
For single location – single-location.php

Thank you! That did the trick. :-)) Is there anyway that I can ‘choose’ the sidebars for EM Pages?

you can try to search – Plugin Widgets on Pages then use wp php code like <?php echo do_shortcode('[widgets_on_pages id=1]'); ?> in the templates
