This Plugin is discontinued.
You might like to take a look at Polylang Sync here on GitHub, which addresses a similar issue.
Manage post relationships like attachments, post parents and ACF Relational fields which are not covered by Polylang plugin.
Tested With WP 4.4.2 - 4.5.2, Polylang 1.8.4 - 1.9, ACF pro 5.x
- Adds a clone post feature
- Clones post attachments to corresponding languages
- Changes post thumbnail and ACF Relations (like post object, image, ...) to their corresponding translations
There are two filters allowing a developer to disable one of the two two features:
// disables the Fix Relationships row action
add_filter( 'polylang_relationships_enable_fix', '__return_false' );
// disables the Create4 Translations row action
add_filter( 'polylang_relationships_enable_clone', '__return_false' );
