My blog posts index page (http://katievb.com/blog/) is showing only 1 blog post at a time; I want it to show more.
I am currently using X Theme as my WordPress theme, but a similar problem happens even if I try using Twenty Fifteen or Twenty Twelve or other standard themes. (The blog index page still just shows 1 blog post.)
I would think it would show 6 per page like this demo: http://theme.co/x/demo/integrity/1/blog/.
I found this similar (very old) question but it did not help me.
It seems like there is a
posts_per_page variable that must be set as
1 right now, and I'd like it to be
But I'm surprised the default would be
1 and that it persists across all themes. Where can I change it, or how can I change my child theme of X?
