Hey Yoran, our sites are a bit different. Yours is thin, whereas we are an SEO-focused network of sites that scale thousands of pages per website.
The subfolders have caused several issues, notably right now after a language translation for slugs has caused mass 404s across the site.
Weglot are trying to assist on the matter, but they seem confused regarding the problem & a solution for me is not assured. This is not the first time this has happened to us.
