Woocommerce and Theme Error

Hi,
Woocommerce plugin is giving a 404 page error when trying to book for a room. Please can you assist with possible solutions.
Secondly, any modification made in the template using WPBakery page builder generate error and the details will disappear from the page when you preview. Beside, the theme is not compatible with Elementor page editor.
Please we seriously need your technical intervention.
Thanks.
