Ok,
it seems the problem could be related to a missing PHP library. You should check the error message in your web server error log.
If you can't get the error message, just try this. Open redj.php in the system plugin foled and find this function:
function sanitizeURL($url) {
//return utf8_encode(substr(utf8_decode($url), 0, VARCHAR_SIZE));
return mb_substr($url, 0, VARCHAR_SIZE, 'UTF-8');
}
So, de-comment the first line and comment the second:
function sanitizeURL($url) {
return utf8_encode(substr(utf8_decode($url), 0, VARCHAR_SIZE));
//return mb_substr($url, 0, VARCHAR_SIZE, 'UTF-8');
}
And check if problem persists...
Let me know,
Luigi
