When you create a competition, the games in the fixture have a status of Draft. You need to publish the games so they appear on your website.
NOTE: you don't have to publish all the games at once.
From Competitions, click Enter Results & Team Sheets.
Find the games you want to publish. You will see a Status of Draft.
Tick the box at the beginning of the row for each game you want to publish.
NOTE: the Publish button will only appear once you have ticked at least one of the boxes.
A box opens for you to review the games that you are going to publish. Click Publish.
The games will now appear as Published and will be on your website.
