Hi Marius, I have updated the code you mention. And I find out I forget to copy resources/js/xwiki/wysiwyg/xwe from the place that I built to the server's resources/js/xwiki/wysiwyg/xwe. Thank you for your help again! Probably this results the problems below: "It this a public web site? Can you create me a temporary account to debug the problem?" It is a server runs on campus (Miami University) network in order to protect it from bad people. Thank you very much for helping me. I really appreciate it. "Can you install the Firebug Firefox extension?" I have successfully installed in on WinXP PC, it seems not work on my vista laptop. Here is the error that I could find under DOM tab: $continue: Error: "throw $continue" is deprecated, use "return" instead filename: " http://wiki.burge.csi.muohio.edu:8080/xwiki/resources/js/prototype/prototyp… " lineNumber: 4725 message: ""throw $continue" is deprecated, use "return" instead" name: "Error" stack: "Error("\"throw $continue\" is deprecated, use \"return\" instead")@:0\n@ http://wiki.burge.csi.muohio.edu:8080/xwiki/resources/js/prototype/prototyp… \n" I did not see any from Script tab.
