Hi sentq, thank you very much for your reply. I am now very interested with namesilo. Is it possible to integrate it with whmcs?
By the way, the current is pending because of paypal - once they go to the checkout process and logged in to paypal, it says that my client successfully paid but he was redirected again to my site's cart. And when I checked on my dashboard, it says that pending payment and his invoice is unpaid.
One of my friend also subscribed and he needs to go to his client account in my whmcs site to pay again the invoice apart from the first signup and payment to paypal after checkout of my site. I am really confused because the client needs to somewhat make a twice payment action on paypal - although they are only charge once, even with the said 2 payment actions (from 1. my site checkout to paypal after login and 2. go to client whmcs account and pay the invoice)
Please help me guys
