This is discussed also in:
but has no recent updates so I'll bring it up again. (plus that it was discussed under a heading that had nothing to do with WPML)
It seems Duplicate Post does not function well with the multilingual WP tool WPML.
I have a blog/site with two languages: English as primary and Swedish as secondary language.
All seems to work fine for English (the primary language).
But in the secondary language the following happens:
If I create a duplicate of a post in Swedish (the secondary language) it makes a duplicate but as soon as the post is saved the post language is switched to English (the primary language).
This has some (grave) consequences but essentially means that Duplicate Post can't be used with WPML:
- the metadata info is lost or screwed up (tags & categories)
- the link between posts in different languages is lost (primary post & translated post)
Since I'd much like to use this plugin I'm hoping for an update that works nicely with WPML.
