Hmm tried again and was still getting the same thing or a much plainer error message "Upload of file failed" if I tried with only 1 image.

However, I then reduced the image size so the file was much smaller (but still above GetDare's stated max size) and voila. I was trying to upload a 4000 x 3000 image that's nearly 3MB, so small in modern terms but clearly too much for the server's today. Maybe it'll fix itself in a few days or I'll have to get used to compressing before uploading. Thanks for checking the system still works Lola!
