This is a problem caused by your template using Bootstrap 3.3.2 (which is newer than the official Joomla version 2.3.2) which conflicts with another Joomla javascript library called MooTools.
We have built a number of workarounds into JEvents to enable it to run on Bootstrap 3 sites but it looks as though we may need another one for this template.
Can you try replacing the content of the file components/com_jevents/assets/js/jQnc,js with this
var jevjq;
function checkJQ() {
//alert(typeof $);
if (window.jQuery && jQuery.fn) {
jevjq = jQuery.noConflict();
}
}
checkJQ();
// workaround for tooltips and popovers failing when MooTools is enabled with Bootstrap 3
// See http://www.mintjoomla.com/support/community-forum/user-item/1833-braza/48-cobalt-8/2429.html?start=20
jQuery(document).on('ready', function() {
// Will be true if bootstrap 3 is loaded, false if bootstrap 2 or no bootstrap
var bootstrap3_enabled = (typeof jQuery().emulateTransitionEnd == 'function');
if(window.MooTools && bootstrap3_enabled) {
var mHide = Element.prototype.hide;
var mSlide = Element.prototype.slide;
Element.implement({
hide: function () {
if (jQuery(this).is("[rel=tooltip]")) {
return this;
}
mHide.apply(this, arguments);
},
slide: function (v) {
if (jQuery(this).hasClass("carousel")) {
return this;
}
mSlide.apply(this, v);
}
});
}
});
Does it help?
