Dear Feldstein,
if you would like show both a Logo and the Site Title in header, then you will need to edit this code in “header.php”:
<?php if ( get_theme_mod('happenstance_logo_url', $happenstance_defaults['happenstance_logo_url']) == '' ) { ?>
<p class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>"><?php bloginfo( 'name' ); ?></a></p>
<?php } else { ?>
<a href="<?php echo esc_url( home_url( '/' ) ); ?>"><img class="header-logo" src="<?php echo esc_url(get_theme_mod('happenstance_logo_url', $happenstance_defaults['happenstance_logo_url'])); ?>" alt="<?php bloginfo( 'name' ); ?>" /></a>
<?php } ?>
in this way:
<p class="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>"><?php bloginfo( 'name' ); ?></a></p>
<a href="<?php echo esc_url( home_url( '/' ) ); ?>"><img class="header-logo" src="<?php echo esc_url(get_theme_mod('happenstance_logo_url', $happenstance_defaults['happenstance_logo_url'])); ?>" alt="<?php bloginfo( 'name' ); ?>" /></a>
Best regards,
