Missing URL for attribute ‘src’ in tag ‘amp-img’.

If you are talking about invalid structured data, this probably because you have not defined a default image in the admin panel for pages that do not have a featured image.

You have this in your AMP page

<ul class="amp-wp-meta amp-meta-wrapper">
		<div class="amp-wp-meta amp-wp-byline">
					<amp-img src="" width="24" height="24" layout="fixed"></amp-img>
		</div>

This is being caused by the fact that you have something running into your post-title-meta. It isn’t obvious at a first glance but I think it is your avatar. That needs to be turned off. In the plugin this is bit of code is firing –

<?php if ( function_exists( 'get_avatar_url' ) && $author_avatar_url ) : ?>
			<amp-img src="<?php echo esc_url( $author_avatar_url ); ?>" width="24" height="24" layout="fixed"></amp-img>
		<?php endif ; 

Try this first of all – in admin settings for “single” for the plugin make sure

Author Bio in Single is off. Test again. Then if it is still doing it try turning meta to pages to off.

If none of this works we are into filtering it out via functions.php.

Comment //

WP total cache is showing debug info in the source on non-amp pages. You should stop that from showing. If the W3TC toggle to turn it off in the admin panel does doesn’t work then this will do it . In functions.php add this

add_filter( ‘w3tc_can_print_comment’, ‘__return_false’, 10, 1 );

Glad you found it. It was not immediately obvious that an avatar was the cause.

Still you should turn off the debug in W3 total cache as it slows the page load down. It also alerts people that you are using that plugin which has had some problems in the past as a target for the baddies. Often even if you turn off the comments from rendering in the source from the W3TC admin it continues to show them. One way to stop it is to use that filter I have given.

You should mark this as resolved if you are happy it is solved.

Looks like comments being rendered by W3TC are no longer showing but you have not deactivated the avatar thing. If you don’t wish to wait for the update you could probably use a remove action from the amp template head. It is probably best to just wait for the update.
