Please be aware you must be a league administrator to gain full access to the league tabs
If you log into Full Time as a League Administrator and the majority of tabs have disappeared from the top you can change this by selecting the setup tab and then Teams. This can happen because the default division the league opens on only has one team in the division. You can change the division to one that has more than one team in and all the tabs at the top will reappear.
You can also change the order of the division by selecting the setup tab and then divisions. Then when you click edit next to a division you will be able to change the rank number. This will then change the division that the page opens on.
