I am trying to get radEditor for ajax, latest release, to work in DotNetNuke 4.8.4. The editor installs, activates, and comes up ok but the toolbars are blank. You can hover over the toolbar and the tooltip appears and you can click on the blank spot and that action performs. I tried the hyperlink and the dialog box appears but the background is transparent. I tried in IE 7, IE 8 beta and Firefox 3 with the same results. Tried clearing the caches with same result. Any ideas?
