hello, each month, my host is taking the hosting bill automatic from my paypal how can i stop this? can i login into my paypal and stop it from there? and how can i do that
It depends on your situation -- if you no longer have hosting with them and they are still charging I would get in touch with them and get some refunds going, then ask them to take you out of the billing system. That is really the best way to handle it.
It sounds like you have a subscription set up in PayPal. Login to your PayPal account to cancel the subscription.
Like tobycoke has said, they can't really just take money out unless you have a payment agreement with them. I would cancel it from PayPal, then definitely contact the host in question though, as to make sure your account is canceled within their billing system.
