Unable to upload photos? [SOLVED/FIXED]

Been trying to upload photos using both Firefox mobile browser & Liftoff app, but both do not appear to be working.

Does not work when attempting to upload both as a post and uploading in post body.

Checked in other instances, and I am able to upload images there.

Do I need special permissions or something? Please let me know!

I took some screenshots of error messages, but obviously I am unable to upload then, so.
