Hi Mr. Fuller,
Thank you for your help. I really appreciated it.
But my case is different. Let me tell you my story. One day, I suddenly found my website could not open, showing the regular “database not connected” that normal mistakes. My first thought is the problem of wp config.php. But I never change that before. How comes the database connection problem. With doubt and curiosity, I open the config.php, whose database,user name and password all are gone, with the default filling in as sample config.php written(I forgot to take screenshot.I rewrite those places with correct user name and password immediately. Then it began to install the wordpress system.
So apparently I did not change the database. What should I do to solve the problem. Thank you in advance.
Best regards
Kevin
