Here’s how you can fix the javascript issue.
If you’re comfortable editing php files, goto the Twenty Plus Pro theme folder and open the functions.php file
A few lines from the top you’ll see a block of code like this
<br />
/* ======[ Load the scripts ]======= */<br />
$wp_scripts = new WP_Scripts();<br />
function nivo_scripts_load()<br />
{ // Deregister the included library<br />
wp_deregister_script( 'jquery' );<br />
// Register the library from Google's CDN<br />
wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js', array(), null, false );<br />
}<br />
add_action( 'wp_enqueue_scripts', 'nivo_scripts_load' );
Remove it, then save the file and upload it back to your theme folder.
This was added when I was troubleshooting an issue with the slider and was supposed to be removed. If you’re not comfortable editing the file yourself, I can do it for you if you use the contact form on the main site to send me an email, or you can wait for the update which should be out in the next few days.
