Problem: You are using the 'Twenty Twenty-four' block theme on your WordPress site and are unable to include the language selector in the top main menu or change menu items for translated pages, as the Appearance > Menus link is unavailable due to the block editor theme. Solution: 1. The Appearance > Menus section is not available with Block Themes, and the settings under WPML > Languages > Menu language switcher do not work with these themes. Instead, use the WPML Language Switcher Block, which can be placed in the header or footer templates. 2. To translate Block Theme Templates, Template Parts, and Navigation Menus, navigate to WPML > Translation Dashboard, create a translation job for each content, assign the jobs to yourself, and then access them at WPML > Translations to complete the translations using the WPML Translation Editor. If these steps did not resolve your issue, it might be helpful to send us the WPML troubleshooting information.
