Background of the issue:
I'm trying to duplicate and publish pages and new posts on my website скрытая ссылка. I've removed all the plugins except WPML and the problem persists. When I remove WPML, the problem is solved, so the problem is with your plugin(s) (WPML Multilingual CMS and WPML String Translation).
Symptoms:
Can't publish pages and new posts when WPML is active.
Questions:
Why can't I publish pages and new posts when WPML is active?
How can I resolve the issue with WPML preventing me from publishing content?
