how to edit footer text

I think there is a theme option to edit this content.

Sorry, that must be for the Pro version only.

You should create a Child theme to make your changes. If you do not, all of your changes will be lost if you update your theme.

You can test this by adding it to the end of your theme’s style.css, but to make it permanent, you should add it to your child theme’s style.css:

.powered { display: none; }

To edit the code, you would have to edit your child theme’s functions.php according to this code from the theme’s inc/catchkathmandu-functions.php:

/**
 * Template for Footer Content
 *
 * To override this in a child theme
 * simply create your own catchkathmandu_footer_content(), and that function will be used instead.
 *
 * @uses catchkathmandu_site_generator action to add it in the footer
 * @since Catch Kathmandu Pro 1.0

function catchkathmandu_footer_content() {
