I have network activated the plugin (v3.6.4 on a wordpress 3.5 multisite/subfolders), but there seems to be a problem with the images on the network admin bar. They have disappeared.
The core.php at the older version 3.6.3 and wordpress 3.4.2 on line 85 reads:
if ( 'div' === $item )
And on v3.6.4 we find:
if ( 'none' === $item )
Now if we change line 85, back to
if ( 'div' === $item ), it corrects the images for the network admin page, but breaks them for the admin pages on the sites returning a new error 404 - not found. :(
I am testing this on a Safari v5.0.6 - Mac.
