Do you have a recent database backup?
I have already done this, nothing. Probably conflicts when you configure the file ‘wp-config.php. I tried to configure it manually but did not succeed
What conflicts with wp-config.php? Can you give us a little more to work with?
prevents me from logging in as administrator, not even allowing me to change password. After you have formatted and deleted the database several times continues to do the same defect for the first time let me in as an administrator, then no more
Try asking your hosts for assistance with this.
