I just discovered (quite by accident) that my site is crashing in IE8 since I installed the theme update.
The only thing I'm seeing in the Chrome error console is the following
Failed to load resource: the server responded with a status of 404 (Not Found)
I'm using the latest WP and the latest BlogsMU via a child theme.
This wasn't happening until the update. It works fine in IE9, Chrome and FF.
Thanks for any advice regarding this matter. =)
