jQuery conflict
<p>I am trying to run the following jQuery to change the text of my username and password boxes so that they do not need a label (inside <code>&lt;script&gt;</code> tags):</p>

<pre><code>jQuery(document).ready(function($) {
    $('#user_login1').val('Username');
    $('#user_pass1').val('Password');
    $('#user_login1').focus(function(){
        $('#user_login1').val('');
    });​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
    $('#user_pass1').focus(function(){
        $('#user_pass1').val('');
    });​
});​ 
</code></pre>

<p>The code works on <a href="http://jsfiddle.net/j6UpH/2/" rel="nofollow">jsFiddle</a> <strong>[updated]</strong> (proving it's a WP issue not a jQuery issue).</p>

<p>I have tried without the <code>function($)</code> modifier and replacing the <code>$</code> with <code>jQuery</code> but to no avail.</p>

<p><del>I am "trusting" the folks that code <a href="http://wordpress.org/extend/plugins/use-google-libraries/" rel="nofollow">Use Google Libraries</a> to sort the jQuery out on my site meaning my jQuery include looks like this: <code>&lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"&gt;&lt;/script&gt;</code></del></p>

<p><strong>EDIT 1</strong></p>

<p>Now not calling it at all, as when I add <code>wp_enque_script('jquery');</code> it breaks the admin pages showing nothing but a blank white page. Never the less jQuery gets called like so:</p>

<pre><code>&lt;script type="text/javascript" src="http://elitetradersgroup.com.au/wp-includes/js/jquery/jquery.js?ver=1.7.1"&gt;&lt;/script&gt;
</code></pre>

<p><strong>END EDIT 1</strong></p>

<p><strong>EDIT 2</strong></p>

<ul>
<li>Changed spelling to <code>wp_enqueue_script('jquery');</code></li>
<li>Changed <code>$</code> in jQuery to <code>jQuery</code></li>
<li>It has become apparent that jQuery is broken site wide, save wp-admin</li>
</ul>

<p>Still not working. </p>

<p>The above location (edit 1) that the jQuery is called from does exist.</p>

<p>I noticed that it calls <code>jQuery.noConflict()</code>  twice. Once in the output of the page, and once at the bottom of the jQuery file.</p>

<p><strong>END EDIT 2</strong></p>

<p><strong>EDIT 3</strong></p>

<p>In response to Chip Bennett here is the call found in <code>functions.php</code> of my theme.</p>

<pre><code>wp_deregister_script('jquery');
wp_enqueue_script('jquery');
</code></pre>

<p>It also occured to me I had not posted up my website for testing, outside of the jsfiddle code. The form I am trying to get working is on the top right of this page:</p>

<p><a href="http://elitetradersgroup.com.au/" rel="nofollow">http://elitetradersgroup.com.au/</a></p>

<p><strong>END EDIT 3</strong></p>

<p><strong>EDIT 4</strong></p>

<p>Replaced the jQuery in edit 3 with the following based off of chip bennett's answer</p>

<pre><code>function wpse45377_enqueue_scripts() {
    wp_enqueue_script('jquery');
}
add_action( 'wp_enqueue_scripts', 'wpse45377_enqueue_scripts' );
</code></pre>

<p>I also thought to look at the console output in Chrome's dev tools and got this:</p>

<pre><code>Uncaught ReferenceError: jQuery is not defined   Line:25
    (anonymous function)
</code></pre>

<p>The code it is referencing is this</p>

<pre><code>25: &lt;script type='text/javascript'&gt;jQuery.noConflict();
26: /* &lt;![CDATA[ */
27: var tb_pathToImage='http://elitetradersgroup.com.au/wp-includes/js/thickbox/loadingAnimation.gif';
28: var tb_closeImage='http://elitetradersgroup.com.au/wp-includes/js/thickbox/tb-close.png';
29: /* ]]&gt; */
30: &lt;/script&gt;
</code></pre>

<p><strong>END EDIT 4</strong></p>

<p>Which is the same version of jQuery that jsFiddle uses so I can't understand why this isn't working. A little help would be much appreciated.</p>
