/!\ This commit *must* be "forced" forward-ported /!\ Recent commit(s) broke existing databases making website videos disappear / not be saved / ... Original code was broken then fixed by a succession of commits which solved some errors to create new ones. Hopefully, this one is the right stable one. Existing databases should be restored while allowing new videos to be added correctly no matter the version. In master, a solution must be found to smoothly migrate old videos to a new better system.
