I realize I should upgrade, it's just a long procedure each time so I put it off until it's necessary.

The error I get in my 404 log is:

Target: 404;http://www.wineintro.com:80/images/general/default/toggle_closed.gif
Referer: http://www.wineintro.com/forum/ubbthreads.php?ubb=showflat&Number=335644&page=1

If I look in the source of that page I see:

var baseurl = "/forum";
...

var open_block = new Image();
open_block.src = baseurl + "/images/general/default/toggle_open.gif";
var closed_block = new Image();
closed_block.src = baseurl + "/images/general/default/toggle_closed.gif";



So as you can see the URL should have /forum/ in it - but it does not.

I did look through the upgrade logs and didn't see this addressed - did I miss it?

Hmm, haven't seen this one before. I'll need to look and see what might be doing this.
