Page Editor

Hi All, I am somewhat new to WordPress.

I maintain two wordpress sites. Both via GoDaddy’s wordpress hosting package.

The first site, which I love, shows me this when I click to edit a page. This is a very simple editor which I adore beyond words.

However, when I go to the second website and click on a page to edit it takes me to this God-help page builder that I dont like.

Can someone tell me how I can have the editor from site 1 into site 2?
