<h4>Website Settings — Full Debug (MODE 1)</h4><h5>CRITICAL Issues Fixed:</h5><ul><li><strong>Page truncated at 7,155 lines (half the page missing):</strong> Two calls to undefined function <code>giveHost()</code> in subdomain_settings.php:30 and js_functions.php:97. The function is defined in index.php (frontend) and as class methods, but NOT available in the settings page context. Each call caused a fatal error that killed rendering. Replaced with <code>$_SERVER['HTTP_HOST']</code>.</li></ul><h5>HIGH Issues Fixed:</h5><ul><li><strong>17 unsafe JSON.parse/$.parseJSON calls</strong> across js_functions.php (10) and branding_js.php (7) — all would crash if PHP warnings corrupted AJAX responses. Added <code>safeParseJSON()</code> wrapper and replaced all calls.</li><li><strong>topbarcss endpoint crash:</strong> Undefined keys <code>$r['sitelinkid']</code>, <code>$r['css_topbar_bg_color']</code>, <code>$r['css_topbar_icon_color']</code>, <code>$r['css_floating_arrow_color']</code>, <code>$r['icon_blend_mode']</code> — all accessed without null coalescing. Added defaults.</li></ul><h5>Retest Results:</h5><ul><li>Page: 16,617 lines (was 7,155 truncated), 0 PHP errors, renders completely</li><li>Endpoints tested: getDomainDetails ✓, displaySubdomain ✓, loadimages ✓, topbarcss ✓</li><li>All JS parse calls wrapped in try/catch</li></ul><p><strong>Files:</strong> subdomain_settings.php, js_functions.php, branding_js.php, controller/websites/websites.controller.php</p>
