I took a two week hiatus from running my campaign. I then logged on, and almost all of my maps are broken. Their uploaded icons/images are shown as broken. I tried the cache clearing, extension editing--everything that was suggested to make sure that things were running properly. All other software seems to be in order, but the images are still broken, resulting in no map images. I do use an API for Dungeon Alchemist, but, again, not all my maps have been affected by this. I noticed throughout the years, this has happened to several other people. And there doesn't seem to be a definitive fix to this occurrence.
