E-Xoopport : Welcome to your new site
If you did a SQL dump, then simply login with Admin/admin (case sensitive), and be sure to change your login information!
Also remember check file permissions on mainfile.php. It must be read-only (0444 unix), and be sure to delete the entire /_install folder from your server for security reasons.
REMEMBER:
To be able to save your configuration data, you need to check that all /cache folders are world writable (0777), and any files in them (0666) even if the setup process should have already done all this!
