Arkadaşlar bu hata nedir? What is this ?

You will be able to create more when winners of your current giveaways confirm them.

You have to wait until your last giveaways are marked received, before making new ones.

Siteye üye olduğunda 3 tane giveaway yapma hakkın oluyor. 3 tane kurunca biri onaylandı işareti gelmeden diğerini kuramazsın. Aynı zamanda her 3 tane başarılı hediyen için bir slot daha kazanıyorsun.

Quoting the FAQ with the reasoning behind it:

- Why is there a limit to the number of gifts I'm able to give away?

We limit the number of gifts a user can create for security purposes, and to prevent a new user from potentially posting a large number of invalid gifts to the site. When you create giveaways and your gifts are received, this number will increase, and you'll be rewarded with the ability to create giveaways with a greater number of copies, or more simultaneous giveaways.
