Well. I had some problem with the “Expire” headers for the images.
After a bit of searching I’ve found that in blogs.php at line 91 there is
@header( ‘Expires: ‘ . gmdate(‘D, d M Y H:i:s’, time() + 100000000) . ‘ GMT’ );
Why you have added this ? Wouldn’t it be better to leave the Expire header under the control of Apache ?
I love WPmu
