Filter by language

Are you using a multi-language plugin like WPML?

Yes, exactly!

Which one? The plugin comes with out of the box support for WPML.

It’s WPML and the plugin doesn’t filter properly the posts from Custom Post Types. How come?

By properly do you mean that it doesn’t pick up the correct i.e single language automatically?

The support is still very preliminary and works on normal posts only.

Yes, in some english posts there are some italian posts displayed. Is it because the Custom Post Types are not fully supported?

I’m still workign on enabling proper support for all post types. I haven’t tested this on custom post types yet.
