How can we resolve the PHP errors related to wpml-cms-nav and sitepress-multilingual-cms?
Welcome to the WPML support forum. I will do my best to help you to resolve the issue.
We can reproduce this error here and it has been escalated to our developers already. This will be fixed in the future version of WPML CMS Nav.
This alert won't affect the normal functioning of your site. As a temporary workaround, we recommend setting debug mode to false by adding or changing the following code in your wp-config.php file, located at the root of your WordPress installation:
define('WP_DEBUG', false);
This should help to resolve the issue until a permanent solution is implemented in future releases. Please try it after a site backup and let us know your feedback.
