So I'm not sure if it was an update that broke my View but I had created a View for the Post Type "Media" to create a gallery. In the loop template I had selected Post URL and wrapped it in <img> which was working. But now it's not because the Post URL is now displaying the media image's page not the direct image link.
It was working previously but now it's not, unfortunately I don't have another site as an example. Basically on the Gallery page it was displaying the media images themselves. When clicking on the image it would open a light box of the thumbnail.
The image links are redirecting to the page you mentioned because it's not working. So, the view changed from outputting the image URL (correct) to the attachment URL (incorrect). Does that make sense?
I suspect that something might have changed on the website given that you say it was working. Are you able to temporarily disable all the non-toolset plugins and try again ?
I've done a test of this on my end and it worked fine on my test site. The images are showing when I add the URL to the img tag.
So I would recommend disabling your non-toolset plugins and checking.
So it turned out that we had a redirect in place to point the media attachment URLs to the images themselves but it was removed. Added it back in and everything works. Thanks for your help!
