Reply To: Header Image getting blurred

What’s the link to your site again?

Have you uploaded your logo to your media page yet? If so, do you have a link to that as well so I can take a look?

You can change the logo size in the functions file by looking for this code –

//* Add support for custom header
add_theme_support( 'custom-header', array(
	'flex-height'     => true,
	'width'           => 300,
	'height'          => 60,
	'header-selector' => '.site-title a',
	'header-text'     => false,
) );

…and then changing it to match the exact size of the image you want to upload. The 300 x 60 is just a default size, you can still change this if you need to. Let me know if you have those links so I can see how the image is supposed to look.
