Trying to Locate Validation Errors

Hi –

My website http://varresa.org has a bunch of validation errors that I am trying to fix. I am new to this and have been unable to find in which files these errors are located! These errors are the results of installed plug-ins, not any code I wrote myself, so I’m a little lost! I’ve looked in about 15 files so far and can’t find the codes. Can anyone point me in the right direction? I need to do this to fix my bottomblock that became misaligned when I added new code the sidebar.php

This is an example of one I am trying to fix:

Line 233 column 683: document type does not allow element “div” here; missing one of “object”, “applet”, “map”, “iframe”, “button”, “ins”, “del” start-tag.

…iv id=”ajax-comments-notification-68″></div><div id=”ajax-comments-68″ class=

The mentioned element is not allowed to appear in the context in which you’ve placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you’ve forgotten to close a previous element.

One possible cause for this message is that you have attempted to put a block-level element (such as “” or “<table>”) inside an inline element (such as ““, “<span>”, or “<font>”).
