Ultimate Branding; GridMarket; Marketpress multisite.
Login Image: The "Browse" button does not work. I tried manually changing wordpress-login.png to logo.png and "save". No luck.
Favicons: I can use the "Browse" button, but tried many files and formats to upload from my desktop. It will not take my images.
I have an issue with the avatar plugin for profiles, and site categories icons; where I cannot upload images here. Maybe these issues are linked.
