I'm currently in the process of submitting a photo to ESP. I have completed all the details and I'm ready to click "Submit" but the Submit icon is greyed out / non-clickable. It seems to be indicating that there is a required field to be completed but I have already completed all of the fields (the ones with red asterixes.) Ive even selected the 'no person' icon. I notice that they now require the date for commercial images which I think is strange but I filled that in regardless. I can save the information I typed in no problem but it won't let me submit. Any ideas what's going on?

Well I tried uploading another image there yesterday and to my surprise, it worked. I didn't do anything differently.
