Re: Accidentally deleted config/config.ini.php, how do I rebuild it?

Let's try different approach. Create a file config/config.ini.php:

; <?php exit; ?> DO NOT REMOVE THIS LINE
; file automatically generated or modified by Piwik; you can manually override the default values in global.ini.php by redefining them in this file.
[database]
host = "127.0.0.1"
username = "root"
password= ""
dbname = "XXX"
tables_prefix = "piwik_"
adapter = "PDO\MYSQL"
charset = "utf8"

[superuser]
login = "root"
password = "098f6bcd4621d373cade4e832627b4f6"
email = "test@test.com"
salt = "3c8f9ca0a238644809fe11b64871e8a3"

replace with your info, then you can login with root and password test
