I submitted a feature request, it was denied.
Reasoning:
They want us to push their products on our customers.
Not all of us want to sell MarketConnect SSL's. I personally have a great relationship with GlobalSign, and want to continue selling GlobalSign SSL's while still offering my clients the AutoSSL feature.
This solution works for me. But it's not feasible in the long run.
WHMCS support gave me this when I asked how to remove it, or at least redirect it:
It doesn't work. You can try, but there's something blocking the redirect. So for example, if your SSL product page is /cart.php?gid=6 it will go to /cart.php still.
WHMCS, why are you pushing us to sell your products to our clients?
Why add this feature?
You should update your Stripe module, or any other module first. And give us the damn option to disable this useless crap.
