I am using Elementor and was creating a Service Page. The sections appear in the Elementor backend but does not appear in the front end/published website at all. I have tried to clear my WP Cache and Browser cache but this did not solve the problem.
Did you update the service page in the Elementor? If not, then you need to update the page in the Elementor after inserting the content in the widget. If you are showing in the front page, then you need to select the Business template by going to the respective page and selecting it under the Page Attributes in the Page editor.
