为什么我的网站http://elancemarket.com/一次又一次地出现这个错误？
Error establishing a database connection
SQL ERROR [ mysqli ]
User elancema_user already has more than 'max_user_connections' active connections [1203]
Warning: mysqli::mysqli(): (HY000/1203): User elancema_user already has more than 'max_user_connections' active connections in /home/elancemarket/public_html/ask/qa-include/qa-db.php on line 66
我使用的是非常昂贵的 VPS！
