Private Custom Post Types - 500 Error When Reviewing Automatic Translations

Overview of the issue

When using WPML with private custom post types, you might experience a 500 error when attempting to review automatic translations before publishing. This occurs because private post types, such as Avada Layouts, do not support front-end previews, even in the original language.

Workaround

You can review and approve the translations directly from the WordPress admin:

• Edit the original language post in the back end.
• Use the language switcher in the top admin bar to switch to the translated version.
• Publish the translation from the editor.

Alternatively, you can approve translations using the bulk action:

• Go to “WPML > Translations”.
• Select the translations that need to be approved.
• Use the bulk action dropdown to select “Approve translation reviews”.
