<h4>Associate Module — Additional Fixes</h4><ul><li><strong>Fixed:</strong> TypeError: Cannot read properties of null (reading 'questionEnabled') on Join button click — <code>checkModuleDetails</code> decrypted null because PHP warnings prepended to the encrypted JSON response corrupted the payload. Root cause: <code>$_REQUEST['LANDINGPAGE']</code> accessed without isset on lines 157 and 828, producing HTML warning text before the JSON. Fixed all 3 occurrences with <code>\!empty()</code>.</li><li><strong>Fixed:</strong> Null guard in JS <code>checkModuleDetails</code> callback — if decryption returns null, falls back to <code>proceedAssociate()</code> directly.</li><li><strong>Fixed:</strong> Null guard in JS <code>getMyProspectRecipientEmails</code> callback — added <code>if (\!data) data = [];</code>.</li><li><strong>Fixed:</strong> Controller <code>checkModuleDetails()</code> null access on <code>$data['termsandcondition']</code> when <code>checkQuestionEnabled()</code> returns null.</li></ul><p><strong>Note:</strong> The YouTube picture-in-picture violations are from YouTube's embedded player (base.js) — external, not fixable.</p><p><strong>Files:</strong> controller/associate/associate.controller.php, platform/module/AssociateManager/extend_js.php</p><p><strong>Result:</strong> All encrypted endpoints return clean JSON. Join Associate button works. 0 JS errors from module code.</p>
