Can’t load short code with AE

I have a site built entirely with Elementor and AE. But since a few days, I can’t update AE (I’m on version 2.16) and some parts of the site (notably the testimonials, the agenda, and an interactive map) can’t be displayed anymore and it seems to me that they were linked to shortcodes. What should I do to fix the problem? Thanks
