Thanks for contacting WPML forums support. I'll be glad to help you today.
I would need to look closely at your site, so I would need to request temporary access (WP-Admin and FTP) Preferably to a test site where the problem has been replicated.
Your answer will be private, meaning only you and I can access it.
❌ Please backup your database and website ❌
✙ I would need your permission to de-activate and re-activate the Plugins and the Theme and change configurations on the site. This is also a reason the backup is critical.
✙ I also need your permission to take a local copy of your site to debug the issue without affecting your live site.
