Yes the same happened to me. The only problem is that the language of the clone is set back to “the main language” (instead of secondary language).
For your second question : “What to do when someone clones the original post (in the “main” language)?” I think that all its translations would have to be cloned as well. This would avoid us to manually relink a primary language post and its translation…
Thanks again for you help.
Thank you for the quick fix!
I have another issue… We are using your plugin in combination with WPML Multilingual CMS Plugin (http://wpml.org/). Everything seems to work perfectly, except when we clone a post in english it clones it in French (the native language of the site). It seems that the clone doesnt keep the language attribute… Anything you can do?
