建立数据库连接时出错

This either means that the username and password information in your wp-config.php file is incorrect or that contact with the database server at localhost could not be established. This could mean your host’s database server is down.

• 您确定用户名和密码正确吗？
• 您确定输入的主机名正确吗？
• 您确定数据库服务器在运行吗？

若您不明白这些术语的含义，则应联系您的主机商。若仍需要帮助，可随时访问 WordPress 支持论坛。
