Bug on layout on multi-site

Hi everyone!

I have been trying to understand my issue, but I can’t! Here it is: I have a website using WP multi-site (subdomains), and I have installed the My Calendar plugin.

The problem is that, on some of the sites the layout of the calendar is alright, but for some it just doesn’t print correctly (widgets and the shortcodes).

site where it’s working: https://cantinedumidi.enchantier.org/calendrier/
site where it’s not: https://drogheria.enchantier.org/calendrier/

Thank you for enlightening me on this!!

Cheers
Sam
