What version of Tutor are you running? And what version of the indigo theme?

Tutor 12.0.0
And the indigo theme freshly cloned from github, following each step of the setup instructions (tried 3 times).

My tutor installation is an update from 11.3.1, update went flawless after enabling mfe and android plugins.

I’m sure you have tried this but in the footer.html file change line 6

from branding.api import get_footer

to

from lms.djangoapps.branding.api import get_footer

@insad My bad, I had pushed the indigo upgrade to our private repository, but not to Github. Please pull in the latest version, which should work just fine with tutor v12.
