Shapely and Polylang : Doesn't switch on front page

Hi Colorlib,
I am using shapely theme with Polylang, which worked fine for the past year.
Also it seems that with last update the landing page refuse to swish to any language.
I have tried to deactivate other plugins, roll back to previous versions, but I get the same :frowning:
All other pages from my website will work correctly and switch to any language.
It ONLY the front page of my web site.

I am running out of ideas.
The website is “tooap”

I believe I may be having the same kind of issue as here:
