Conflict with plugin MEC Lite by Webnus

Hi

Eleganto PRO 1.6.0
Modern Events Calendar Version 6.2.0

Have noted that the Menu on the Header and Footer are not displayed on the Single Events page. Examples are:
https://indofrenchhub.com/events/atelier-de-conversation-niveau-b2-c1-12h-batch-ii/
https://indofrenchhub.com/events/delf-b2-intensive-course/
https://indofrenchhub.com/events/dalf-c1-intensive-course/
https://indofrenchhub.com/events/production-orale-ecrite-preparation-au-delf-b2/

We contacted Webnus, who replied asf:

Please contact your theme author, MEC, just load on theme content (content.php on this image):
