HELP! Media won't show in posts.

What media specifically? Can you link to a page that is supposed to have this media?

https://gndphotography.net

the investment page and blog type posts specifically

Can you link to one of those pages?

https://gndphotography.net/investment/

What type of media is missing from that page, and how did you try to add it?

I have it set up as a page and went to edit it. I clicked “add media” and uploaded the two images that I would like on the page. Then I clicked “insert into page” and nothing appears.

Can you switch to the Twenty Fourteen theme and deactivate all plugins to narrow down the issue?
