Change text on "Create new Account" button makes administration created user registration fail In the form provided by user_registration_form(), I modified the text for the "Create New Account" button to "Sign me up!" via the following code:

$form['actions']['submit']['#value'] = t('Sign me up!');


Creating a new account as anonymous user from the main site works fine: new button text, customized validation and submission included. Now, if I want to create a new user as administrator via "People -> 'Add User'," the form and button are correctly displayed, but NOTHING happens once I hit the button! Somehow, all validation and submission routines seem to be deactivated by renaming this button. Do you have any idea why this is happening?
That code works without a problem for me. I hope you didn't change the code in Drupal's user module directly?

You should make this change by implementing hook_form_alter() in your own custom module or theme. 

function MODULENAME_form_user_register_form_alter(&amp;$form, $form_state, $form_id) {
     //your changes here
   }
