Change the number of posts on the blog page?

This used to be a setting somewhere, but I can't find it any more

Go into your theme and edit it, go to the Source Code tab and in the packages.json file the "page-size" value is what you want to adjust. The default is set to 6 on the Blog template.

You're probably remembering that there used to be a point-and-click way to edit this value on the sidebar of the template editor. I just restored this function and if you open up the template editor, you should be able to edit the Number of posts per page in the sidebar once again

For the record, the other answer is correct in terms of editing the source code for the template. The sidebar inputs simply offer a point-and-click way to manipulate the values in package.json.

Thank you!
