Hi, On a brand new installation of Drupal 6.13, after I told Drupal about my database, I got the following set of messages: . warning: Parameter 3 to block_user() expected to be a reference, value given in C:\xampp\htdocs\drupal\includes\module.inc on line 450. . warning: Parameter 3 to comment_user() expected to be a reference, value given in C:\xampp\htdocs\drupal\includes\module.inc on line 450. . warning: Parameter 2 to dblog_user() expected to be a reference, value given in C:\xampp\htdocs\drupal\includes\module.inc on line 450. . warning: Parameter 2 to node_user() expected to be a reference, value given in C:\xampp\htdocs\drupal\includes\module.inc on line 450. . warning: Parameter 3 to system_user() expected to be a reference, value given in C:\xampp\htdocs\drupal\includes\module.inc on line 450. . warning: Parameter 2 to user_user() expected to be a reference, value given in C:\xampp\htdocs\drupal\includes\module.inc on line 450. . : Function ereg() is deprecated in C:\xampp\htdocs\drupal\includes\file.inc on line 895. How is this likely to affect my Drupal installation and what do I need to do about it if it's not a good thing? Thanks. Jim
