If you're experiencing a critical error when trying to create or sync menus between different language versions, it might be due to a conflict with your theme, particularly if you are using a child theme or a customized theme.
Solution:
First, ensure that you have not made any modifications to the parent theme that could be causing the issue. We recommend downloading the latest version of the theme (WoodMart in this case) and installing it on your staging site to see if the problem persists. If the issue continues, try switching to a default theme like Twenty Twenty-Four or Twenty Twenty-Five, create the menu, and manually translate it into English. Afterward, you can switch back to your original theme.
If this solution does not resolve your issue or seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket at WPML support forum.
