I am trying to modify the old website which used wordpres for blog. After I downloaded the wordpress 321, follow the instruction, then come to the step: wp-admin/install.php. I did. The it says I am already installed, to reinstall, I have to delete the record on the table. I don't know where to delete. Second, I tried to log in, used the username and password I set up for my databse connection used in wp-config.php, can not let me in.
What should I do?????? Please help me.
