Hello,
I change the module.sanitizer.php [as recommended in 'comments'] and the follow warnings appears
Quote:

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/xxxxxxx/public_html/vx/class/module.textsanitizer.php:576) in file /include/common.php line 248

Warning: Cannot modify header information - headers already sent by (output started at /home/xxxxxxx/public_html/vx/class/module.textsanitizer.php:576) in file /include/common.php line 257

something to do?
cheers

    session_start();

There are additional space characters at the end of your file.

Open textsanitizer.php, and ensure there is nothing after the final "?>" at the end of the file (IMO there is an empty line in yours)
