designsimply on "[Theme: Sorbet] Remove "Proudly Powered by Wordpress" from footer"

One possible way would be to hide it with CSS either using a child theme or a CSS editor such as the one that comes with the Jetpack plugin.

Here is an example CSS snippet that will hide that text:

.site-info {
	display: none;
}

I have removed the code from footer.php but it still appears...

That sounds like it should have worked. Maybe you didn't remove the right code?

Editing theme files directly is not advised because if you update the theme your changes would be overwritten. You could make this modification using a child theme though. To do that, set up a child theme, copy the footer.php file into it, and remove the following lines of code from the new footer.php file:

<?php do_action( 'sorbet_credits' ); ?>
			<a href="http://wordpress.org/" rel="generator"><?php printf( __( 'Proudly powered by %s', 'sorbet' ), 'WordPress' ); ?></a>
			<span class="sep"> | </span>
			<?php printf( __( 'Theme: %1$s by %2$s.', 'sorbet' ), 'Sorbet', '<a href="http://automattic.com/" rel="designer">Automattic</a>' ); ?>
