Hi there,
We updated the jQuery library that was calling an outdated version in our theme. The calendar was working for a while after this update, and now is suddenly not working again. When you click on the link to our calendar, the page appears blank. Can you take a look and give me some direction as to why this is not functioning now.
Thanks
Suzanne

Hi Dale,
Your theme is still using an outdated version of jQuery (1.6.1). We recommend using what is automatically included in WordPress (currently 1.8.3).
When working with a few of our customers, I’ve noticed something like this in the theme’s functions.php:
function super_cool_theme_js() {
if (is_admin()) return;
wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js');
wp_enqueue_script( 'jquery' );
}
While the intentions here may be good (loading up jQuery from Google’s CDN can make the site load faster), this can create problems down the road if the theme does not get updated. jQuery is a very active project, and updates are released at a fairly rapid pace.
Since WordPress will continue to update the version of jQuery that it bundles, by running this version you’ll get the benefit of the latest features and bug fixes of the current version. This also avoids compatibility issues, as most plugin authors are developing and testing with the version of jQuery that is bundled with WordPress.
One possible way to fix the above example would be to remove the lines of code that swap out the bundled version of jQuery, leaving:
wp_enqueue_script( 'jquery' );
Note that there are many different ways to include jQuery, so the way to fix this might be a little different with your specific theme.

Hi, since your last email, we did update to Verion 1.8.3 version of Jquery and that caused the URL not to function properly. The site would not appear when you placed a www. in front of the URL, however, the calendar was working.
Now we used JQuery updater to update to the most recent version of JQuery 1.9.1 and the calendar is not working again, but the URL issue is fixed that was causing issues to the ht access.
Please advise, I can have pasted the original reference to 1.8.3 code above.
thanks
//Making jQuery Google API
function modify_jquery() {
if (!is_admin()) {
// comment out the next two lines to load the local copy of jQuery
wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js', false, '1.8.1');
wp_enqueue_script('jquery');
}
}
add_action('init', 'modify_jquery');

You might try the beta version of the calendar available in the pre-release channel that you can opt in to from your account page. WordPress hasn’t updated to 1.9.1 yet, so a lot of plugins haven’t been updated for jQuery 1.9.1 yet.
