Thanks for contacting WPML forums support. I'll be glad to help you today.
Could you please edit this product in the default language and update it? Also, please try to delete the redirection and check if it will work correctly.
If that didn't help, 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 if possible –
in order to be of better help and check if some configurations might need to be changed.
Your next answer will be private, which means 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.
