If you are using Elementor Pro 3.3.1 for your WordPress website, you may notice your elements in Pro all locked, and a note at the bottom of your site editor that says: Activate your License and get Access to Premium Elementor Templates, Support & Plugin Updates.
If you go to your Plugin page and click on “View Details” under Elementor Pro, you will see that the plugin is missing.
Seems like there’s a problem with the latest version of Elementor Pro.
Suggested action plan:
Backup your website (We use and recommend Backup Guard).
Install an older version of Elementor Pro:
Activate this older version.
You may restore your backup if you like, if not you can actually keep working on your website.
Hope this helps. 🙂
