Gallery will not let me upload

Okay....I've tried every fix I've found thus far, but nothing seems to be working. I cannot upload anything to gallery. I can download from the gallery, and my lots and households will save to my library, it is just uploading. It gives me a server error every time.

I've tried...

-restarting the game

-reinstalling the game

-deleting all mods

-resetting the resource file

-clearing cache

-created a backup sims 4 file, and forced a new folder, still does nothing. Even with a 'blank slate'

I really have no idea what else I can do to make it work. Any suggestions?
