How do I run it on previous versions? And would switching to enfold theme be an easy transition from replete? i’d like to make this easy

I have the Replete Theme Template. My website is experiencing an issue where the full content of the homepage is not loading properly. The main front page slider image fails to load and the product image sliders are supposed to be 1 row each in which a user can scroll through various products however, the site is showing all of the products at once (incorrectly). This may be a javascript issue or something similar. It mat have happened as of a latest update. I have tried to activate and deactivate various plugins to see if the issue gets fixed but it has not. Can you assist?

Hey, I am having a problem with the advertisement area not properly linking to the link I am trying to apply. So when I click the advertising are on the front end it doesn’t follow anywhere, just refreshes the screen. How can I fix that?
