Waypoint support active causes map to not display

When activating waypoint support in Settings, all maps are not loading. If I leave waypoint supoort inactive in Settings, and then use the attribute waypoints=”true” in the shortcode, same result – map doesn’t load when waypoints=true. in linked page, here is shortcode for first map (not loading) : [sgpx gpx=”/wp-content/uploads/gpx/Addo2025-100Mile-Elevation-Final.gpx” waypoints=”true”] here is shortcode for 2nd map on same page (working) [sgpx gpx=”/wp-content/uploads/gpx/Addo2025-100Mile-Elevation-Final.gpx”] Both maps use the same GPX file. Here is sample waypoint code from the gpx file: <wpt lat="-33.311126095" lon="25.503628179"> <ele>331.0</ele> <name>ECHO</name> </wpt> wordpress 6.7.2, php8.2, wpgpxmax 1.7.11 NOTE: I have modified wp-gpx-maps-util.php file as per this post as the plugin crashes my entire site otherwise: https://wordpress.org/support/topic/patch-for-php-8-error/ The page I need help with: [ log in to see the link]
