Background of the issue:
I am trying to resolve a critical error that occurs when I click on the WPML > Translation management tab in the WordPress backend. The rest of the site works fine in both the backend and frontend. Here is the link to the page where the issue can be seen: 隐藏链接
Symptoms:
A critical error occurs only when clicking on the WPML > Translation management tab.
Questions:
Can you please check the issue with the Translation management tab?
