If this helps, I’ve just compared 2 page source files; one which worked [ver 1.2.0] against one which doesn’t [ver 1.3.2] & these are the only 2 differences I could see in the output:
ver 1.2.0 has this:
<link rel="EditURI" type="application/rsd+xml" title="RSD" href="https://www.mydomian.co.uk/xmlrpc.php?rsd" />
<link rel="wlwmanifest" type="application/wlwmanifest+xml" href="https://www.mydomian.co.uk/wp-includes/wlwmanifest.xml" />
<script type='text/javascript' src='https://www.mydomian.co.uk/wp-includes/js/comment-reply.js?ver=20081210'></script>
and 1.3.2 has this in its place:
<link rel='stylesheet' href='https://www.mydomian.co.uk/wp-content/themes/aeros/nggallery.css?ver=1.0.0' type='text/css' media='screen' />
<link rel='stylesheet' href='https://www.mydomian.co.uk/wp-content/plugins/nextgen-gallery/shutter/shutter-reloaded.css?ver=1.3.0' type='text/css' media='screen' />
<link rel="EditURI" type="application/rsd+xml" title="RSD" href="https://www.mydomian.co.uk/xmlrpc.php?rsd" />
<link rel="wlwmanifest" type="application/wlwmanifest+xml" href="https://www.mydomian.co.uk/wp-includes/wlwmanifest.xml" />
<script type='text/javascript' src='https://www.mydomian.co.uk/wp-includes/js/comment-reply.js?ver=20081210'></script>
