Still the no reflection found error

[aurur818]

So yesterday i was just first trying this tool cus i was just curious, and i typed with thsi command python xsstrike.py -u http://testphp.vulnweb.com/categories.php?PO6=hack --headers "Cookie: security=low; PHPSESSID 504b8f12c03878b9317dba31e49819c5" --skip-dom, but everytime i started it kept showing the no reflection error even i provided the cookies to the web

So if this bug can be patched/fixed or if someone good at it, might be needed some method to fix it

Hope someone can help!
