I am the only one here? I uploaded a bunch of images that need to be resubmitted for missing a detail

.
Now I am unable to either resubmit them or even can barely redo a fresh upload, I keep getting a BLANK page. Very annoying

.
I work with Safari on a Mac, and tried with Chrome and same story. Anybody experienced the same and found a solution? I know it comes from their programming, but we never know. Thank you!
