When making CSS edits using the on-the-fly editor, the Save button doesn't save anything and no notification appears to indicate anything was saved. Others have reported the same issue in Discord's #help channel.   When typing in the on-the-fly editor, this error appears in the console on every key press: GET https://www.worldanvil.com/w/attr 500 (Internal Server Error)   When clicking the Save button, this error appears in the console: jquery.min:4
POST https://www.worldanvil.com/api/world/5e5b03da-9ed9-4c24-a9c5-6d4e50720ff1/update 500 (Internal Server Error)

ajax @ jquery.min:4
