I need some assistance editing the Clients Testimonials section on the homepage. I would like to rename the section, “Patient Testimonials” as the site I am working on is for a dentist. Also, I am unable to change the background image of the section. It is defaulted to a person writing on a notepad next to a laptop. I would like to replace this background image with an image from my media library. When attempting to upload my desired image into the section area in Theme Options, the default image still appears.
