Can't view individual images after upgrade.

I created the slug hair-images after upgrading and I can’t access the images.

I can see the image thumbnail on the gallery page but when I click the thumbnail the gallery just reloads.

Here’s an example on HairWeGo (The affected website): http://hairwegoproducts.com/all-images/images-celebrity-hair/pictures-of-hayley-williams-signature-red-hair/

Any help resolving would be appreciated.
