This is an issue caused by bad style customizations. Can you get into the control panel? If so, you'll need to look at the "customized components" page and consider reverting some style properties. Specifically, it relates to one where the property was changed from a yes/no checkbox to a full CSS definition.

You should try to revert that style property and then complete the master data rebuild again.

No, I mean finish the install process as that hasn't finished properly. It give you an option to rebuild the master data.
