Elementor Pro works with almost all themes & plugins seamlessly.
If you do run into a plugin conflict, our support and development department will do everything to fix the issue.
If you run into an issue with your theme, your theme support will be able to fix the problem by contacting us and/or by checking our documentation for developers. You also have the option to switch to our barebone Hello Theme, in this case.
If we can’t solve your issue, you can always use our 30-day refund policy and get your money back.
