I'm trying to install OTRS 6 Free versión, with the /otrs/installer.pl tool. But I'm getting this recurrent error when trying to create the system database (step 2):
Can't create otrs database. Database already exists.
I've checked that, previous to the database create process, not otrs user nor otrs database exists. This mariadb server is in the same host as otrs.
Any ideas about the error? I've tryed with several database/username names without success.
