Images not optimizing?
- • Check PHP memory limit (256MB recommended)
- • Verify GD or ImageMagick is installed
- • Check file permissions on uploads folder
- • Review error logs for specific issues
WebP not serving?
Ensure your server supports WebP mime type and .htaccess rules are properly configured. Check browser dev tools network tab to verify WebP delivery.
