Help with PHP Fatal error!!

Hi Dan, I have Buddy Community Stats installed in the main page of a BP multisite, where BP is root on a subdomain. And the theme I use works with the page builder plugin SITEORIGIN.

When I go to insert the Stat widget into a row, I get the following error:

[28-Sep-2017 22:46:45 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function bp_is_register_page() in /home/mysite/public_html/wp-content/plugins/buddy-community-stats/bp-community-stats-widget.php:49

Any ideas what I can do, besides leave the widget out?

Thanks!
