Go to pages and create a new one. Chose the appropriate template from the page attributes box on the side (Can’t see the box? Click on “Screen Options” on the top right and activate it.) You can chose between the Gallery, team, portfolio and clients template.
Save your choice. Now you have to create items for the side you created. To create a new team member for example just go to “Team-Add new” in your backend. It works the same with all post types. The options are always below the main editor. If you can’t see them click on “Screen Options” on the top right and activate them.
