Hi, I just noticed that none of my forum posts are visible after enabling this module. It makes no difference if the forum is enabled for translatability or not.
Not sure yet if that is a bug or something with my setup.

Could you confirm if forum is working with this module?

Obviously I have applied all the patches, and the menu and node translations are working fine.

A bit of digging indicates that the sql query that retrieves the forum posts is rewritten to include a where clause on the translatable table even when the content type forum is not activated for translation.

In particular, the function translatable_db_rewrite_sql on lines 664-670 of translatable.module tries to detect the content types used by a query and to stop rewriting when this content type is not enabled, but this doesn't work with the query from the forum module.
