 * I’m hitting a brick wall with this one. I’m trying to use a newer version of 
   jQuery (1.7.1) by unloading and reloading the script with this code, in my theme’s
   functions.php file:
 *     ```
       function modify_jquery() {
       	if (!is_admin()) {
       		wp_deregister_script('jquery');
       		wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js', false, '1.7.1');
       		wp_enqueue_script('jquery');
           }
       }
       add_action('init', 'modify_jquery');
       ```
   
 * When I try this locally I can see in Firebug that the new version is loaded. 
   But when I upload to my server the default version is always loaded… Any idea
   of what I can try?

 * That’s **older** than the version of jQuery bundled with WordPress core. Never,
   ever, de-register core jQuery. It causes all kinds of problems.

 * Ah, thanks mate that put me on the right track knowing the default was higher.
   Seems that some other bloody plugin was loading an older version.

 * Where did you download the bad plugin from?

 * Was trying to find a decent image gallery slider. Got them off this site. Think
   it’s time to make my own though, the ones I tried are crap and I need something
   very basic.

 * Have you had a look through the [existing gallery plugins here](http://wordpress.org/extend/plugins/search.php?q=gallery)?
   Maybe you could use something like [http://wordpress.org/extend/plugins/lazyest-gallery/](http://wordpress.org/extend/plugins/lazyest-gallery/)
   as a starting point and hack it to suit your needs? Beats re-inventing the wheel.

 * Thanks, I’ll take a look at that one.
