String positions in MySQL start at 1. So you actually need

SELECT SUBSTRING(REPLACE( DATE_SUB(CURDATE(), INTERVAL 1 DAY),"-", ""), 1, 6)
AND NOT (user_name LIKE '%AWB%' OR user_name  LIKE '%Bot%' OR user_name LIKE'%bot%' OR  user_name LIKE '%BOT%' OR user_name ='CommonsDelinker')
GROUP BY page_title,user_name
HAVING   Edits > 2
ORDER BY   page_title ASC, Edits DESC
LIMIT 100;
