[Plugin: Polylang] 404 Error on all Pages

I just checked the page it and it’s fine.

did you solve the issue? I’m having a similar problem with all me translated pages.

I had to change all my permalink settings to the defaults with the ?page_id= in the URL and it worked. Still haven’t been able to get it to work with pretty URLs.

Yes, the exact same thing solved it for me. I miss the pretty permalinks though. Translation is more important though…

Did you check for any plugin or theme conflict?

I know this post is rather old, but thought this might be useful to anyone with the same issue: we could quickly see that any plug-in that tingles around with permalink structure is a possible cause. In our case it was a custom post type plugin which, in combination with polylang, would return “404 error” in every static page except for the main home.

The solution was rather simple, as it only took a visit to the “permalinks” settings and refresh the selected structure. This is in fact a recommended step every time a “link-sensible” plugin is activated/deactivated.

Hope it helps, and congrats for this excellent plug-in!!
