CSS syntax error in tag ‘style amp-custom’ – bad url.

I found that’s related to Instagram embed. There are 20 posts error, all contain Instagram embed.

Any solution?

Hi,
Try;

/**
 * DAF: Fix validation error of base64 images in stylesheets.
 */
add_filter( 'the_content', 'daf_fix_amp_space' );
function daf_fix_amp_space( $content ) {
	if ( function_exists( 'is_amp_endpoint' ) && is_amp_endpoint() ) {
		return str_replace('data:image/png; base64,', 'data:image/png;base64,', $content);
	}
	return $content;
}

Hope it helps
