The Studio app that is served on port 18010 shows with no theme. It only shows black text on a white background and with no images... that happens while the other counterpart LMS (on port 80) app shows fine.
Where shall I start troubleshooting this problem?
The edX Studio does not support to theme.
If you are not able to see the default pictures Use following commands to update asset files
paver update_assets cms --settings=aws
