Dear Grand Challenge:

I have received the verification email and have verified. But when I click "+ Host your own challenge", it shows the error like this:

  • You need to verify your account before you can do this, you can request this from your profile page.×
  • Forbidden
  • You do not have permission to access this content.

But when I verify in my profile, it shows the errors:

  • Email hosted by cannot be used for verification due to abuse. Please contact support to verify your account another way.

How can I post my own challenge?

Best regards
