The requested site does not exist

Hi,

I’ve bee trying to use Forminator on a multisite installation, but each time I try to edit the form, I get the following error “The requested site does not exist”.
Here’s a link to see what happens (real short gif file) : https://img.perspectives.marketing/animation.gif

So far I had 0 problem using Forminator, and that includes other mutisites instalations ; the only difference here is that I didn’t develop this site, I came by after its launching. I’m wonderig what could be causing this error: the site was developped on a subdomain, could this be the cause for this (as if all tables in the database had not been changed.

I’d be grateful if you had any pointers regarding this matter

Yours,
