Edit qtranslate_utils.php, line 143 from this:
$date_parameters[] = ‘#%#’; $strftime_parameters[] = ‘%%’;
to this:
$date_parameters[] = ‘#%#’; $strftime_parameters[] = ‘%’;
It seems the extra percentage sign makes it so the percentage sign in the format gets interpreted as literal percentage signs and therefore they don’t get parsed by strftime().
