Map not uploading

I've been trying to upload one of my maps into one of my games, but it doesn't seem to be working. I've tried the following: - Disabling my browser extensions - Clearing my cache - I checked that my maps are either in jpg or png format - Both maps are under 10MB - The storage I have under my account is around 20/100MB Is there something that I'm not doing right or is it a problem with the maps themselves? I've been using Dungeonfog for making these maps and it worked just fine until this specific map.

I just tried uploading it and it worked fine. Are you dragging and dropping it or going through the file explorer?

With the free account, it would need to be under 5MB.  That might be the issue.
