The problem is caused by a spoiler hack I’m using for the forum.
<script language="JavaScript" type="text/javascript" src="<?php echo site_url(); ?>/wp-content/plugins/mingle-forum/js/spoiler.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#mingle-spoiler-view li').click(function () {
var text = $(this).children('p');
if (text.is(':hidden')) {
text.slideDown('200');
$(this).children('span').html('-');
} else {
text.slideUp('200');
$(this).children('span').html('+');
}
});
});
</script>
I included it in the header.php of the theme, do you have any clue why it is conflicting with the calendar script?
