<h4>Newsfeed Single Post Avatar Fix</h4><ul><li><strong>Fixed:</strong> User avatar not displaying on single post page — singlepost.php had its own local copy of identifyIfUserOrCompany() at line 613 which still hardcoded https:// protocol. The site runs on http:// so the avatar URL (https://152.youportal.lcl/...) failed with ERR_CONNECTION_REFUSED. Applied same fix as newsfeed_list.php: dynamic protocol detection, null guard for companies, fallback for missing accounts.</li></ul>
