Header logo disappeared in child theme

Here is the URL for our website, a child these of Generatepress. There should be a logo to the left of the “Bringing the Arts to Our Community” tagline. The logo has been set in the Customizer. Here is a screenshot: http://www.coastalartsguildct.com/wp-content/uploads/2016/05/CAGCT_Customizer_Logo.jpg

I’ve checked the header file and all looks OK. Here is the logo section of the header.php file:

<?php if ( !empty( $generate_settings['logo'] ) ) : ?>
				<div class="site-logo">
					<a href="<?php echo apply_filters( 'generate_logo_href' , esc_url( home_url( '/' ) ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><img class="header-image" src="<?php echo $generate_settings['logo']; ?>" alt="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" /></a>
				</div>
			<?php endif; ?>

Here is a screenshot of the source code showing the logo section is missing: http://www.coastalartsguildct.com/wp-content/uploads/2016/05/CAGCT_Header_Code.jpg

This just happened in the last day or so. Any idea what is causing it?
