I don't really use the sidebox area so thats probably why removing those lines didn't work for me.

I'll give you all the info I have on my test server: I am using the module http://vinosdefrutastropicales.com/i...products_id=46 which bought the script conflict to light for me.

Using Firebug, I can pinpoint that the error is on line 382 of index.php

Firebug is flagging

NotFoundError: Node was not found - 3 repeats
The line in question is marked in red:

Code:
objXHR.prototype.handlePrice = function () {
  var thePrice = document.getElementById('productPrices');
    thePrice.removeChild(loadImg);
  
  // use the spans to see if there is a discount occuring up in this here house
  var test = thePrice.getElementsByTagName('span');
  var psp = false;
Exact printour of console (if this helps):

I am aware that I have 3 additional modules in place. That unfortunately in beyond my control.

I hope at least some of this helps. As I said, I appreciate any help. :)
