gtranslate_perm function contains sample code.

Found sample code from permission function was left in from onthisdate example code.

Is:

function gtranslate_perm() {
    return array('access onthisdate content');
} // function gtranslate_perm

Should be:

function gtranslate_perm() {
    return array('access gtranslate content');
} // function gtranslate_perm
