At the beginning I would like to thank you for a great plugin :)
And sorry for my poor English.... ;)
Ok - So I have a website in two languages.
The default language is Polish and in Polish comments work great.
But now i dont know how can i get the same comments in my English version of site.
To translate my site i use Polylang plugin.
I create "Guestbook" page in English related to Polish "Ksiega Gosci" site and in both sites i inserted [comment-guestbook] shortcode.
I will be very grateful for any help and ideas to make it work in both languages.
