Css and jquery broken on django 2.2

[scwall]

Hi, I am migrating an old project from django 1.6 to version 2.2. I have been gradually moving up the versions and currently django page cms is not working on django 2.2 . There are problems with the distribution of static files.
The other static files of the other modules seem to be well distributed in the administration part though
