Great contribution! I had issues with mb_convert_case() on line 1570 of seo.class.php and I had to change it to
$anchor = preg_replace($pattern, '', strtolower($string));
Is this going to cause me any problems (like hackers, etc?)
Also, I noticed that it only includes words that are 4+ characters in the name it generates from the product name. Does anyone know how to change that to 3+ and if that will make a difference? Thanks!
