I am having the same problem.
I am trying to implement
Lightview.
This is what I have pasted into the Header section of the Master Page:
<link href="~/CMSScripts/lightview.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src='~/CMSScripts/prototype.js'></script>
<script type="text/javascript" src='~/CMSScripts/scriptaculous.js'></script>
<script type="text/javascript" src='~/CMSScripts/lightview.js'></script>
What am I doing wrong, or is there a better way to do this?
I am using PortalEngine and am on version 4.0 of Kentico CMS.
