Background of the issue:
I updated WPML to version 4.7.6 and attempted to update the translation of a product page. I clicked on the round 'arrows' to update the translation, checked 'Translation complete,' and clicked 'Save and close.' However, the page remains stuck at 'Saving in progress.' The issue can be seen on the Dutch translated page: hidden link. I expected to see the Dutch translation on this page.
Symptoms:
The page stays blocked at 'Saving in progress,' and the majority of the Dutch page content disappeared from the website.
Questions:
Why is the translation not saving after updating to WPML 4.7.6?
How can I restore the missing content on the Dutch page?
