took over WordPress website

Dear Forum:
I bought a business with an existing website in WordPress. When I updated, the “Meet the Owners” page, I must have done something which changed how the site used to open. It used to have colorful slides that changed with graphics and stuff. How can I restore how the page used to open?

Many thanks. I’m not a coder. In fact I’m a real dummy about this stuff. But I was able to do a pretty decent job on redoing the “Meet the Owners Page” just as a regular joe.
