Upgraded from WPMU 2.8.4 to WPMS 3.0.1.
Then upgrade the previous Edu Clean theme to the new one 2.1.3 but now the logo/header image is not displayed.
In fact it displays an "edublogs homepage" image.
I went to Edu-Clean Options. Then under Top Header CSS Settings, the image/logo url location was correctly displayed. For an unknown reason (i'm still a rookie) the image/logo is not displayed in the site.
I also tried to access the image directly pasting the url of the image in my browser and cannot see it.
