We've been using version 3.5, so I wanted to update to 3.7.
First I updated Moodle to the last patch 3.5.6+ (Build: 20190614) and did the same with the modules questionnaire and swf as suggested.
Then, using git, I switched to version 3.7 using the commands bellow:
$ git branch --track MOODLE_37_STABLE origin/MOODLE_37_STABLE
$ git checkout MOODLE_37_STABLE
When I tried to run Moodle, I've got 500 error message. I put in debug mode then I've got the messages bellow:
This page should be using theme clean which cannot be initialised. Nor can the site theme clean. Falling back to boost

I copied clean theme and questionnaire and swf modules from 3.5 version, but it didn't work.
Any ideas about what is happening?
Thank you very much.
