If the "Club bet now" button is either taking you to your personal Ladbrokes account or simply refreshing the home page it will be because of one of the following reasons..
Reason 1. It is not your turn to bet
Reason 2. You are not paid/active in the round
Reason 3. Please make sure that you are not already logged in to your personal Ladbrokes account in another tab.
Try on a different browser/device and see if you get the same result.
Reason 4. Please check the status of your personal Ladbrokes account that your account is active and not in review. You can contact Ladbrokes support on 1300 523 276 to check the status of your account.
