my problem is quite annoying and weird. I have created a custom Wordpress theme and in the header.php I was loading jquery like this (can't remember why right now):
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript"> google.load("jquery", "1"); </script>
Last night I replaced the code above with
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
and then my site collapsed. I changed it immediately back again, but the problem persisted. I placed some Jquery in the HTML and it works just fine. Then I disabled my plugins by commenting out code in my functions.php file as below:
<?php
if (!is_admin()) {
wp_register_script('custom', get_stylesheet_directory_uri().'/js/custom.js');
wp_enqueue_script('custom');
wp_register_script('blockui',get_stylesheet_directory_uri().'/js/jquery.blockUI.js');
wp_enqueue_script('blockui');
wp_register_script('fancy',get_stylesheet_directory_uri().'/js/jquery.fancybox.js');
wp_enqueue_script('fancy');
wp_register_script('jeasing',get_stylesheet_directory_uri().'/js/jquery.easing.js');
wp_enqueue_script('jeasing');
wp_register_script('friendchooser',get_stylesheet_directory_uri().'/js/jquery.friendChooser.js');
wp_enqueue_script('friendchooser');
wp_register_script('zclip', get_stylesheet_directory_uri().'/js/jquery.zclip.min.js');
wp_enqueue_script('zclip');
}
?>
Still the problem occurs. Any ideas?
