Editing a web application developed with yii

I know it might sound dumb, but I’m new to this framework. A client has an application that was developed with yii, now he needs some few changes made, like some spellings, changing the content of the copyright on the footer. I tried editing using Dreamweaver, but I don’t seem to locate any of the texts. Please help! Thanks in advance.

Firstly you need a basic knowledge on yii to learn how use it.

Check for documentation.
