Comment to 'Why is a list limited to a max of 31 items?'
  • LeonidS is right, the limit of 31 values are needed for 32 bit system, if you have 64 bit system then you can increase this limit to 63 values, to do it add the following line in the beginning of your inc/header.inc.php file:

    define('BX_DOL_INT_MAX', PHP_INT_MAX);
