MySQLi Connection error

[eluser]Atasa[/eluser]
Hello everyone,
I was very happy to see all these changes and progress to ci with version 1.7,
especially to the Validation class.
Please someone can confirm this...
There is an error coming out saying that Unable to connect to database with the provided settings.
For sure in 1.6.3 I was able to connect therefor I enabled the logs to see what's wrong.

Surprisingly the error was:

Severity: Warning --> mysqli_connect() expects parameter 5 to be long, string given /srv/www/ci/admin/system/database/drivers/mysqli/mysqli_driver.php 63

On line 63 exists the function db_connect(), and I am not using it.
I use the function db_pconnect() beacause I have set it to TRUE in my config file.

Any comment will be appreciated
