I have problem on my site. After updating the WPML to 4.6.6 and string translations to 3.2.8. I cant save products anymore. If I wait a lot I got error "Connection lost. Saving has been disabled until you are reconnected. This post is being backed up in your browser, just in case"
To troubleshoot the issue further, I would need to take a closer look at your site. So would you please mind sharing temporary access (WP-Admin and FTP) to your site? Preferably to a test site where the problem has been replicated.
I have enabled a private reply for you to share the credentials securely, which means only you and I have access to it.
IMPORTANT: Please take a complete backup of the site first to avoid data loss.
✙ I would additionally need your permission to make a copy of the site with plugins like Duplicator and deploy it on my local machine to test the issue further.
