Hello, Mady,
Thank you for contacting us and for using XStore.
1/ If you want to use the Elementor Pro plugin for a single product page, you need to disable our Single Product Builder via Theme Options, then follow the documentation of Elementor Pro plugin. In case, you face a problem or need a guidance, please contact the plugin support, because the Pro version of Elemento does not come bundled with our theme.
2/ We did not test Woolentor with our theme. You can try to use it, but we are unable to provide support for 3rd party plugins.
We hope for your understanding.
3/ In case you decide to use our Single Product Builder, we will be able to assist you but you will need to disable previously mentioned plugins, to prevent conflicts.
Kind Regards,
8theme team
