3 problems

copy pasted the code:

<script>
(function(i,s,o,g,r,a,m){i[‘GoogleAnalyticsObject’]=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,’script’,’//www.google-analytics.com/analytics.js’,’ga’);

ga(‘create’, ‘UA-46689849-1’, ‘thaisereizen.nl’);
ga(‘send’, ‘pageview’);

</script>

into the default page of the template

The problem with the jce popup is related to the template and had something to do with the tabs.
Ofcourse i asked JCE about this… see below discussion:

the media box cannot be used on a page with any kind of a tab module, is there a way to solve this?

Like on this page
http://thaisereizen.nl/nieuw/rondreizen/luxe-rondreizen/droomstranden.html

I’ve deleted the tabs, instead i’m using a menu, but it stil doesn’t work.
No popups… cliking on the image… opens in an new window

Their answer:

This function on your site :

do_nothing( function() {

SqueezeBox.initialize({});
SqueezeBox.assign($$(‘a.modal’), {
parse: ‘rel’
});
});

where can i find that and how to change it???

I don’t know where this script comes from, perhaps your template or another extension you have installed.

is causing an error, which is preventing other scripts after it from executing.
