<h4>Chat Module — Image Protocol &amp; Session Fixes</h4><ul><li><strong>Fixed:</strong> ERR_CONNECTION_REFUSED for company logo images — User.class.php and ChatModuleController.php hardcoded https:// in identifyIfUserOrCompany() image URLs. Changed to detect protocol dynamically from $_SERVER["HTTPS"], so images load correctly on both http and https environments.</li><li><strong>Fixed:</strong> Undefined array key warnings in chat_email.class.php — $_SESSION["activeacctid"] and $_SESSION["uidfk"] accessed without null check during class construction. Added null coalescing.</li><li><strong>Fixed:</strong> Undefined array key "Domain_live" in ChatModuleController constructor — $_SESSION["Domain_live"] not set. Added null coalescing fallback.</li><li><strong>Fixed:</strong> Undefined array key "activeacctid" in getContactList — added fallback to $this-&gt;activeacctid when POST parameter not provided.</li></ul>
