I think there are a lot of difference in charset/collation....
MySQL charset: UTF-8 Unicode (utf8)
MySQL connection collation: latin1_general_ci
stories tables: collation: latin1_general_ci
topics table: collation: latin1_german2_ci
global.php: define('_CHARSET', 'ISO-8859-1');
mainfile.php: did not set anything...
// Set the database charset if applicable
if (defined("XOOPS_DB_CHARSET")) die();
define( 'XOOPS_DB_CHARSET', '' );
Anyway I know that my site is not UTF-8, so I just change the charset in global.php to ISO-8859-1 then it worked fine when I upgraded to XOOPS 2.4.1/2, but when I upgraded to XOOPS 2.4.3, then I had this issue...
