This is probably a dumb question, but I can’t, for the life of me, figure out how to add in the testimonials?
You’ll have noticed that the theme tells you it recommends installing the Jetpack plugin. Install and activate Jetpack, and in Jetpack activate the “Custom content types” extension. Then go into Settings -> writing and enable ‘Testimonials’. You’ll now be able to add Testimonials as a custom content type in the usual way under Posts.
Thanks so much!
