Please, slugfy format, does not support utf-8
The correct one is sao-paulo and not so-paulo.
correct the file by putting 2 lines of code.
in dmxConnectLib/lib/formatters/text.php line 58
replace with
function formatter_slugify($val) {
if ($val == NULL) return NULL;
$a = 'ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜüÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûýýþÿŔŕ"!@#$%&*()_-+={[}]/?;:.,\\\'<>°ºª';
$b = 'aaaaaaaceeeeiiiidnoooooouuuuuybsaaaaaaaceeeeiiiidnoooooouuuyybyRr';
$val = utf8_decode($val);
$val = strtr($val, utf8_decode($a), $b);
$val = strip_tags(trim($val));
$val = strval($val);
$val = preg_replace('/[^\w\s]/', '', $val);
$val = strtolower($val);
$val = preg_replace('/[_\s]+/', '-', $val);
$val = preg_replace('/-+/', '-', $val);
$val = preg_replace('/^-/', '', $val);
return $val;
}
this solves the problem.
