Cách làm

1. Mở file /js/admin.js. Sao lưu file
Bước 1: thêm hàm strUnicodeToAscii
function strUnicodeToAscii(str){
 str = str.replace(/[\'\~\@\#\%\^\&]/g,'');

 str =  str.replace(/[\u0105\u0104\u00E4\u00E5\u00E0\u00C0\u1EA3\u1EA2\u00E3\u00C3\u00E1\u00C1\u1EA1\u1EA0\u0103\u0102\u1EB1\u1EB0\u1EB3\u1EB2\u1EB5\u1EB4\u1EAF\u1EAE\u1EB7\u1EB6\u00E2\u00C2\u1EA7\u1EA6\u1EA9\u1EA8\u1EAB\u1EAA\u1EA5\u1EA4\u1EAD\u1EAC]/g,'a');

 str = str.replace(/[\u00E7\u010D\u0107\u0106]/g,'c');

 str = str.replace(/[\u0111\u0110\u010F]/g,'d');

 str =  str.replace(/[\u00EB\u0119\u011B\u0118\u00E8\u00C8\u1EBB\u1EBA\u1EBD\u1EBC\u00E9\u00C9\u1EB9\u1EB8\u00EA\u00CA\u1EC1\u1EC0\u1EC3\u1EC2\u1EC5\u1EC4\u1EBF\u1EBE\u1EC7\u1EC6]/g,'e');

 str = str.replace(/[\u00EC\u00CC\u1EC9\u1EC8\u0129\u0128\u00ED\u00CD\u1ECB\u1ECA\u00EE\u00EF]/g,'i');

 str = str.replace(/[\u0142\u0141\u013E\u013A]/g,'l');

 str = str.replace(/[\u00F1\u0148]/g,'n');

 str =  str.replace(/[\u00F2\u00D2\u1ECF\u1ECE\u00F5\u00F6\u00F8\u00D5\u00F3\u00D3\u1ECD\u1ECC\u00F4\u00D4\u1ED3\u1ED2\u1ED5\u1ED4\u1ED7\u1ED6\u1ED1\u1ED0\u1ED9\u1ED8\u01A1\u01A0\u1EDD\u1EDC\u1EDF\u1EDE\u1EE1\u1EE0\u1EDB\u1EDA\u1EE3\u1EE2]/g,'o');

 str = str.replace(/[\u0159\u0155]/g,'r');

 str = str.replace(/[\u015B\u015A\u0161]/g,'s');

 str = str.replace(/[\u0165]/g,'t');

 str =  str.replace(/[\u00F9\u00D9\u1EE7\u1EE6\u0169\u0168\u00FA\u00DA\u1EE5\u1EE4\u01B0\u01AF\u1EEB\u1EEA\u1EED\u1EEC\u1EEF\u1EEE\u1EE9\u1EE8\u1EF1\u1EF0\u00FB\u00FC\u016F]/g,'u');

 str = str.replace(/[\u1EF3\u1EF2\u1EF7\u1EF6\u1EF9\u1EF8\u00FD\u00DD\u1EF5\u1EF4\u00FF]/g,'y');

 str = str.replace(/[\u017C\u017A\u017B\u0179\u017E]/g,'z');

 str = str.replace(/[\u0153]/g,'oe');

 str = str.replace(/[\u00E6]/g,'ae');

 str = str.replace(/[\u00DF]/g,'ss');

 str = str.replace(/[^a-z0-9\s\'\:\/\[\]-]/g,'');
 str = str.replace(/[\s\'\:\/\[\]-]+/g,' ');
 
 return str;
}

 2. Tìm hàm str2url và sửa lại như sau
Code
function str2url(str,encoding,ucfirst)
{
 str = str.toUpperCase();
 str = str.toLowerCase();

 str = strUnicodeToAscii(str);
 str = str.replace(/[ ]/g,'-');
 str = str.replace(/[\/]/g,'-');
 
 if (ucfirst == 1) {
 c = str.charAt(0);
 str = c.toUpperCase()+str.slice(1);
 }

 return str;
}

Bước 3 tìm hàm strToAltImgAttr sửa lại như sau
{codecitation}
function strToAltImgAttr(str,encoding,ucfirst)
{
 str = strUnicodeToAscii(str);
 
 if (ucfirst == 1) {
 c = str.charAt(0);
 str = c.toUpperCase()+str.slice(1);
 }

 return str;
}
3. Mở file /classes/Tools.php
Tìm hàm link_rewrite và sửa lại như sau
Dòng 150
static public function link_rewrite($str, $utf8_decode = false)
{
$purified = '';

$length = Tools::strlen($str);



//remove any '-' from the string they will be used as concatonater

$str = str_replace('-', ' ', $str);
