Are there Pro/paid features used for demo creation?

After purchasing the theme there is no need to buy any extensions or plugins, all the functionality shown on the demo is included to the theme archive. Our themes are Elementor-based and you can edit them using the basic Elementor plugin.

Besides  themes come with the custom CMSMasters Elementor addon plugin bundled for free that provides you with an extended functionality.  Here you can find more info about it. 

Personal assistance is provided via the tickets system. Should you have any questions please submit us a request at https://cmsmasters.net/help-center/ with the link to your site and relevant WordPress and FTP credentials and our support agents will take care of it.
