Hard Reject for My PHP Script, Can anyone help?

Hi All,

I just submit my first CodeCanyon script. It is a PHP script which allows you to create your own WhatsApp Click-to-Chat service. I am sure my code is well written and well documented but not sure why I got rejected. This is the email I got.

Thank you for your submission. We have completed our review of “QuickWA - Start Your WhatsApp Click-to-Chat Service” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again

Demo for the application:

List of URLS

Username: admin
Password: quickwa123

Documentation:

Can someone give me insight what was the cause my script being rejected, is it because commercial issue, design or etc?

Thank you in advance,
Rio
