Thanks for your reply.
I ended up backing up my database and recreating my home page from that. For some reason it worked fine after I deleted and re-created the page (my settings in reading were already OK so no idea what was causing it)
I am thinking that maybe I restored from the backup before I installed polylang the first time and maybe that’s what caused the problem? In any case, everything is fixed now.
Thanks
Did you ever figure it out? I am running into the exact same problem with very similar settings.
I tried with most combinations of settings on the language settings page and nothing works.
I have a few sites on which I run polylang without this problem (and they have very similar settings too!)
