Thread:Extension talk:BlockAndNuke/ban.php error - column "upload" does not exist/reply (2)

That's a bug.

At this line:

Change double quotes with escaped single quotes on that line:

From: '(rc_new = 1) OR (rc_log_type = "upload" AND rc_log_action = "upload")'

To: '(rc_new = 1) OR (rc_log_type = \'upload\' AND rc_log_action = \'upload\')'
