All changes are visible on both pages

Hi
I posted a comment on another thread but I thought maybe you’d prefer if I post a new one.
So, here is my problem.
I have install you Page Builder Plugin which worked perfectly until I installed polylang as well.
The thing is, when I make a change on the english page (like, well, translating the contents in english !), it changes everything on my french page as well.
I tried to select another theme, to desactivate all my plugins, to update everything I could… Nothing worked.
The only thing which makes me say that the problem comes from the Page Builder Plugin is that I desactivated it, and polylang worked perfectly (by my website doesn’t look good anymore !).

Could you help me on this ?

Thanks a lot

Christophe (from Paris, so please… pardon my english ha ha )

PS : I still try to find a solution on the URL I gave you on this form… so don’t know what you’ll see when you’ll visit the website !
