Is there a way to edit the text “thank you for creating with WordPress

in version 3.3.1 at the bottom of the CMS? If so what file do I need to edit?

Credit definitely goes to @kaiser, but here is a full working solution. You can add this code to your functions.php file (in your theme):

function wpse_edit_footer() {
    add_filter( 'admin_footer_text', 'wpse_edit_text', 11 );
}

function wpse_edit_text($content) {
    return "New Footer Text";
}

add_action( 'admin_init', 'wpse_edit_footer' );

Just hook into the filter. The only thing remaining will be the <hr />.

/**
 * Change/Disable the footer text line
 * @return void
 */
function wpse_remove_footer()
{
    add_filter( 'admin_footer_text',    '__return_false', 11 );
    add_filter( 'update_footer',        '__return_false', 11 );
}
add_action( 'admin_init', 'wpse_remove_footer' );

In case you want to change it:

add_action( 'admin_init', function()
{
    add_filter( 'admin_footer_text', function() {
        echo "This is a custom admin footer text";
    }, 11 );
    add_filter( 'update_footer', function() {
        echo "This is a custom footer update text";
    }, 11 );
} );

Ok thanks, I don’t want to remove it though, just edit what it says.

@Rob Just replace the __return_false callback fn for admin_footer_text with a custom callback that does a return with your custom string.

add_filter('admin_footer_text', remove_admin_footer_text, 1000);

function remove_admin_footer_text($footer_text =''){
return '';  
}

add_filter('update_footer', remove_admin_footer_upgrade, 1000);

function remove_admin_footer_upgrade($footer_text =''){
return '';  
}

Please post a proper answer, that is, please explain what your code does and how it works. File an edit and comply

There you go:

// Admin footer modification

function remove_footer_admin () {
    echo '<span id="footer-thankyou">Developed by <a href="https://www.example.com" target="_blank">www.example.com</a></span>';
}

add_filter('admin_footer_text', 'remove_footer_admin');
