I was working on a codeigniter project from wampserver and it ran perfectly but now I change to a mac and install the project in mamp and throws me the following error
A Database Error Occurred Unable to connect to your database server using the provided settings. Filename: core / Loader.php Line Number: 347

Everything is fine because in Wamp I ran perfect.
