I’m trying to add services and clients, but I don’t see the options in my left config menu. I also didn’t find how to add the services to the front page instead of a new page.
You must install the Custom Post Types Plugin then import the Settings file whoch can be found at point 3. in Our Documentation: https://athemes.com/documentation/sweetheat/
Also, please read Our documentation / watch video tutorials for further info about how to add services, if you can’t find something there, please feel free to ask here on support forums.
Who is the author of the plugin? There are several with similar name.
