I need to add 2 more courses in the courses tab to 8. It allows me to put the number and adds the boxes, but there is no place to enter the information for those new boxes.
Same happens with the Why Academy tabs, both in the number of boxes and in the right hand side information.
By default, WordPress is set to show ten posts per page. To change the number of pages go to the Settings menu > Reading sub-menu.
On the page that opens you will see Blog pages show at most.
Type the number of posts you would like to display and click on the Save Changes button at the bottom of the page.
