It would appear that there is some sort of conflict between Multisite Analytics and the Business Pro 4 theme from CyberChimps. The conflict causes the theme’s administration panel to load incorrectly (though it remains [sort of] usable).
I’ve already created a staging area in order to deactivate all plugins and then test them one at a time to ensure that the conflict is, indeed, with Multisite Analytics. As the conflict generates a fairly large number of warnings and errors, it might be easier simple to provide credentials instead of posting them all here. Please let me know to whom I should direct the email with login credentials.
