   I am by no means a programmer and have added many plugins to my WordPress installation.

   When I view my site using Internet Explorer, I receive a script error on the page (which does not say much I might add):
   
Line: 83
Char: 2
Error: 'null' is null or not an object
Code: 0
URL: http://test.spirko.net/vw


   The strange thing is I do not receive this error using FireFox. I understand this is not that much information, but I really could use anybody's help.

   What version of IE are you using?

   I would search the Microsoft forums. I did see some references when I did a google search on that error. Can you identify your plugins that use javascript?
   Maybe also try a hard refresh (Ctrl-F5) to see if the error goes away.

   I have the same IE version and don't get that error when I go to your site.

   Thanks, I will try that. I just did't know where to start since this is such a generic error.

   One good thing is it doesn't seem to be affecting anything.

   You guys need to dump IE and get a more developer friendly browser.

   your error is in livepreview.js and thus, the livepreview plugin:

   var commentArea = document.getElementById('comment');
commentArea.onkeyup = function(){

   commentArea is null because there is no comment form element.

   You can fix it by just adding a :

   if (commentArea != null) {
commentArea.onkeyup = function(){
...
}
}


   Oh, and don't forget to tell the plugin developer about the issue.

   Edit: hadn't yet seen the immediately prior post before posting this;
   ----------------------------

   On your site I get the following error in Firefox:

   "Error: commentArea has no properties
   Source File: http://test.spirko.net/vw/wp-content/plugins/livepreview.js
   Line: 82"

   The JavaScript is looking for something with id of "comment" and not finding it.

   I use the same plugin as jspirko and I get the same error message in IE. I tried VaamYob's fix (even copying jspirko's modified script directly), but to no avail. The error is reproduced on two different blogs with different setups.
