Hi, there, just upgraded to CI 1.7, however my app reports "Unable to connect to your database server using the provided settings."
After some investigation, I think it is because of the new "port" support for mysql/mysqli. (My app uses mysqli).
By default, in DB_driver.php, $port = ''. And in mysqli_driver.php, the db_connect() function just use this empty port, so there is an error. If I remove the $this->port in this function, my app works again.
But in mysql_driver.php there is a check for port, so no problem.
It is a bug I think.
