This can happen for two reasons:
1. Your friend accepted the invitation, but did not confirm his email address. Ask a friend to check their mail and confirm their email address by clicking on the button in the letter that came from Equalibra upon registration. If the letter has not arrived, your friend needs to make sure that the address is specified correctly in the profile settings. Once confirmed, you and your friend will each receive 7 days of free reading.
2. You have already received the maximum number of registration bonuses, which is easy to check on the accrual status page. But you'll still get 30 days of free reading every time a referred friend pays for their first subscription.
