Branding plugin breaks down the homepage

Hi Team,

We update Wordpress to 3.6 and than we install the Ultimate Branding plugin. That works fine.

But when we network activate the plugin the homepage of all the website, in the entire network, will be blank:

How can we fix this problem?

Now we have to delete all the plugin files and then it's working fine again, but we like to use the ultimate branding plugin.

Thank you in advance for your help.
