Hi there,
Thanks for writing in! I can see there is an image adding by a plugin :
<img width="1" height="1" src="http://bornaware.org/wp-content/plugins/cookies-for-comments/css.php?k=5087d44a1fe26488f5fd32bfa3ec18a4&o=i&t=52232488" alt="css.php">
Let’s see what you are using related to “cookies-for-comments” and disable this to get expected result.
You can also try this CSS under Customize > Custom > CSS to fix this temporarily :
body > img {
display: none;
}
Hope this helps.
Cheers!
