Problem:
If you're experiencing an issue where you cannot see or select your existing WordPress menus in the backend under Appearance > Menus, despite the menu count being visible, this might be due to a conflict with the User Registration & Membership plugin.
Solution:
We recommend taking a full backup of your website before making any changes. To resolve this issue, you can disable the problematic part of the User Registration & Membership plugin code. Add the following code to your site's functions.php file or via a code snippet plugin:

add_action( 'init', function(){<br />    remove_filter( 'user_registration_get_endpoint_url', 'ur_filter_get_endpoint_url', 10 );<br />});

Please be aware that this modification might cause some side effects with the User Registration & Membership plugin. It is advisable to contact their support and explain the situation, highlighting that the issue stems from their use of the SitePress class instead of the recommended WPML developer API. For more details on the WPML API, you can visit WPML Hooks Reference.

If this solution does not apply to your case, or if it becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. Should you need further assistance, please do not hesitate to open a new support ticket at WPML Support Forum.
