    Seeing the following fatal on thousands of sites since 4.3.0 update when having older versions of Pro:

    Hi @mtg169,

    As NickB mentioned below, this Dependency_Exception fatal error is caused by a compatibility issue when running Elementor 4.3.0 alongside older versions of Elementor Pro (specifically 3.11 through 3.32). In those older Pro versions, the Menu module depends on the nested-elements experiment, which 4.3.0 has marked as hidden.

    To resolve this on your sites, you have two options:

    1. Update Elementor Pro: Update to Elementor Pro 3.33.0 or later, as the Menu module no longer has that dependency in newer versions.
    2. Rollback Elementor: Temporarily roll back the free version of Elementor to 4.2.4 and disable auto-updates until you are ready to update Elementor Pro.

    If you are locked out of wp-admin due to the fatal error, you can rename the wp-content/plugins/elementor-pro folder via SFTP to regain access and run the updates.

    Hope this helps get your sites back up and running!
