I created a child theme from the previous theme “Striker” but even when switching to the original themes the uploads did not work. I tried re-installing the themes folder but it did not show the pictures again. Here is an image I tried to upload https://pichost.me/1336990/

The website I am working on is
https://web.ics.purdue.edu/~bwellma/Flaherty/wordpress/index
I am trying to upload images from my computer, none from the internet, using WordPress’ upload feature to create a custom header. I am not trying to upload the picture as a post.
