Tested and working 100% on PrestaShop 8.1.7 + PHP 8.3 (Cloud panel + LiteSpeed)
Results before → after (mobile):
- Performance: 48 → 94
- Largest Contentful Paint: 4.8s → 1.6s
- Total Blocking Time: 720ms → 80ms
- Cumulative Layout Shift: 0.32 → 0.01
Installation tip (very important!):
1. Install the module normally
2. Go to module settings → turn ON "Combine, Compress and Cache"
3. Enable "Defer JavaScript" + "Lazy Load Images"
4. Clear full cache (PrestaShop + LiteSpeed + browser)
WebP conversion works perfectly, even with the free version. No conflicts with JX Mega Layout or Creative Elements.
Big thanks
