Any solution for this problem yet? I’m having the same issue.
I’m running wordpress 4.2.2 on my own personal server. I have php setup so that phpinfo reports that the memory limit is 512 meg, so that shouldn’t be an issue. The images I’m trying to upload are 8688 x 5792, 8.0 meg in size. The reason I want to upload and have images that size in a post is because the new camera I just bought outputs images of that size. I’m posting images from the new camera along with images from my previous camera to provide the photography community images for comparison purposes – so I have a valid reason for wanting to upload images this large.
As others have stated, I can’t find any error log messages that tell me why it’s failing, just that it is.
