Catchable fatal error:
 - Argument 4 passed to moodle_database::set_field() must be an array, string given,
 - called in admin\modules.php on line 62
 - and defined in lib\dml\moodle_database.php on line 1165

lines 61 and 62 in "admin\modules.php" appear not to be necessary.
so one workaround is just to remove the offending lines
        // REMOVE 61: $DB->set_field('course_modules', 'visible', '1', 'visibleold',
        // REMOVE 62: '1', array('module'=>$module->id)); // Get the previous saved visible state for the course module.
