I am running version 4.05.01.
I believe I found the problem. I have some javascript in my skin.ascx page to allow the background image of the header to replace upon reload. Once I commented out that code, the File Manager worked fine.
This leads to a follow up question... Is it possible to have javascript within you DNN skin? Here is my beta site: http://www.fpcurbana.org/
The random image in the header is real plus for the site and I would like to keep it in. Any ideas on how I can keep this feature and have the File Manager work? Thanks.
ps - here is the js I am using in the header:
<script type="text/javascript">
<!--
if (document.getElementById) { window.onload = swap };
function swap() {
var numimages=15;
rndimg = new Array("/Portals/0/header-bg/bg-1.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-2.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-3.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-4.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-5.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-6.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-7.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-8.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-9.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-10.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-11.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-12.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-13.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-14.jpg", "/Portals/0/FPCU-Developer/header-bg/bg-15.jpg");
x=(Math.floor(Math.random()*numimages));
randomimage=(rndimg[x]);
document.getElementById("header").style.backgroundImage = "url("+ randomimage +")";
}
//-->
</script>
