<ul><li><strong>CRITICAL:</strong> Fatal Error on Testimonials admin page — <code>count(): Argument #1 must be of type Countable|array, null given</code> at <code>testimonials.php:21</code> — <code>$testimonials</code> was never initialized before <code>inc_testimonials_manager.php</code> included the file directly on page load (no AJAX prefetch)</li><li>Fix: added <code>$testimonials = $testimonials ?? []</code> guard at top of both admin (<code>services/websites/modules/module/TestimonialsManager/page/testimonials.php</code>) and member-facing (<code>platform/module/TestimonialsManager/page/testimonials.php</code>) view files</li><li>Changed <code>count($testimonials) > 0</code> to <code>!empty($testimonials)</code> — null-safe check in both files</li><li>Added <code>$acctDetails = $acctDetails ?? []</code> guard to prevent undefined variable warning on initial load</li><li>Cascade: previous agent reported fixes but did not actually resolve the Fatal — page remained broken</li></ul>
