Still getting a black screen when clicking or tapping a photo in a post.

Also, getting a security token error if trying to upload 4 or more photos from an iPhone 7 on iOS 11.2. If photos are modified or cropped from the original, there is an upload error also. Taking a screenshot of said modified photo and uploading that will work at the expense of image quality.

The attached image is from a 4-image upload. Dropping to 3 images in one shot worked fine. Clicking on hose images in that post showed a black screen after posting. Had to enlarge and download image to see it.
