+1 to Howard's advice/suggestion.
Core themes have changed in 3.7.x. Clean is not among the core 3.7.x themes.
Suggest adding a line to config.php:
$CFG->theme='boost';
And manually purging the caches in /moodledata/cache ... that's moodledata/cache.
Those will be rebuilt as site is used, but this time using boost theme.
Strongly suggest, then, going to plugins where you can remove a theme and remove 'clean'.

Thank you for your answer...I will need help as I'm in trouble

So I added the line :$CFG->theme='boost';
I manually purged the caches...
As a result :
1/ the boost theme appeared but my id were not anymore recognised...(I don't get it as it should not be linked)
2/So, I retrived the boost line in the config file to see if I could login with the usual theme: it worked
3/ I used the admin panel to change the theme to boost
4/ I cleared the theme cache
5/ I went back to my courses to check the way it behave
NEW pb : I could not get the turn on the edit button on the page, nowhere.
6/ I logged out to check my teacher account
7/ Surprise : my teacher's id were not regognised, I could not log in...
8/ I tried once again the admin account...and I'm back to square 1 : I can't log in with my id under the boost theme and I can't change it anymore as I'm out of control, I have no access to the admin panel.
Any idea?

Edit : if I press the forgotten password link, I get the classical email, I can change my pass, I can get it but after the first logout I can't get in...
