I have noticed for some time now that some of the codes (that use jquery) produce an error in IE.    If you are using a code that is changing, adding something, etc in your topics, message bases it is more then likely the code that is causing the problem.     Save your headers/footers.   Wipe out the codes then check again and Im betting you will not see those errors.  Its not a forum software bug -  it is something not quite correct with one of the codes you are using.

I realize that, but something isn't the same between the two files because if I remove
<script src="http://pspunleashed.smfforfree4.com/jquery.js"></script>
and just keep
<script src="jquery.js"></script>
not all the codes in my footers will work properly.

EDIT: Nevermind, I've figured it out.
