Hey, I’ve found the solution to this issue now.

Basically, IE was interpreting the $.get() call as a cross-domain request, possibly because of URL-rewrite or something similar. I fixed it by adding:

jQuery.support.cors = true; // force cross-site scripting (as of jQuery 1.5)

This could be a security weakness if not handled carefully though.

I also changed the $.get() request to the $.ajax() request to enable error messages(in “eme_calendar.php” on line 404):

$j_eme_calendar.ajax({

type: 'GET',

url: "<?php echo site_url(); ?>",

data: {

eme_ajaxCalendar: 'true',

calmonth: parseInt(month,10),

calyear: parseInt(year,10),

full : fullcalendar,

long_events: showlong_events,

category: cat_chosen,

author: author_chosen,

contact_person: contact_person_chosen,

location_id: location_chosen <?php echo $jquery_override_lang; ?>

},

success: function(data){

tableDiv.replaceWith(data);

jQuery('#calendar_header .eventful a').tooltip();

jQuery('#calendar_header .eventful-pre a').tooltip();

},

error: function(xhr, type, exception) { alert("Error: " + type + "  Exception: "+exception); }

});

In case anyone encounters the same problem…
