that's exactly what the page should look like
crap, ok no error on windows becuz upper/lower cases doesn't affect but on *nix it does.
i was trying not to hardcode "MySQL" incase some of us were using the other databases supported by CI.
i think the best way now is to write a "converter" to link between the full lowercase given by $DB->dbdriver (based on all the possible CI dbs) and the way casing is done in oauth-php.
will patch this into next version.
