Can't buy anything on Humble Bundle

Do you have something like ghostery ?

Open it in private window and try agai.

It may be some addon or extension or w/e that is messing it up.

Thanks for propositions, but I was trying on clean browser, without VPN, adblock or anything =/

You can try it on your phone or contact your bank, they may need to enable the card for online/international purchases.

Why you ask us? There is a Humble Bundle support -.-

to much multibuy transactions, they got you finally and blocked your payments methods (yes, they can do that)

Is it a pre-paid card? Like where you deposit money in it to buy stuff, like a debit card.
Skrill hates pre-paid cards and doesn't accept it, I can't pay with my pre-paid card too and I use my CC to buy stuff there.

Have you tried a different browser? I've never tried a debit card.

Do you have a ban on your account? Have you ever done a chargeback? If you are being automatically cancelled when you try to place an order then something isn't right.. it could be a lot things. You need to contact support and ask why you are auto declined.

Strange, never happened to me. Maybe the problem is in Paypal and not Humble Bundle? If it's a new card, did you renew it on Paypal, so they can charge you?
Try not using VPN, they can see if your location is constantly changing when you're logging in on your account and thus can block the access because it might be someone trying to steal your account, but they wouldn't know that. Contact support and they will help you. ^_^

Did you, by any chance, buy an obviously large amount of the same bundles/games on a regular basis? Because HB is the only bundle site which is incredibly allergic to people trying to resell their stuff and they tend to block users who obviously farm keys from them. (Which is ironic, when you think of sites like IndieGala or OutakuMaker which essentially subversively encourage reselling.)

Hi bro,
Added you on Steam to discuss something

I have got the same problem..... but if I pay with the paypal account of my girlfriend, it does work

This is what I got when I try buy Humble Monthly:

Only thing i can suggest is to look over they knowledge article, and then contact a ninja (Humble Support Staff) at the bottom of this thread: https://support.humblebundle.com/hc/en-us/articles/206558898-Purchase-failure-assistance

Hi there!

Thanks for contacting Humble Support! Unfortunately, due to abuse from some users, we are unable to accept payment from prepaid credit cards for the Humble Monthly at this time. You can still purchase the Monthly using a non-prepaid card or PayPal. I sincerely apologize for the trouble. If you have any other questions or concerns, please let me know. Have a good day!

Thanks!

Ok, I was dumb. I got limit for internet transactions set to zero, that's why I got blank background after trying :p
Thank you all for help anyway :)
