With the release of Genesis 2.10 (UT WordPress framework), all theme settings have been moved into the WordPress Customizer. This change affects how the custom header logo is set.
Your UT WordPress header logo can now be set in the WordPress customizer. Just go to Appearance -> Customize -> Header Logo. See the page below for more instructions on customizing your header logo.
