Customize/Edit a website script so that it functions correctly on mobile devices

Greetings! I need a programmer that can customize a script. I have purchased the script here: [login to view URL] But some of the script functionality does not work on mobile devices. I want someone that can edit the script and make it work on mobile devices. On mobile devices the custom pages do not show content The content is called by shortcodes from the admin panel. I think the problems is a mix of problems with javascript and css. Current website and other details will be given in PM. You will be asked to answer the following questions when applying: What questions do you have about the project? Have you went to [login to view URL] to get an idea of the script?
