Hi sanchii91,
Thanks for writing and providing the info you did. That helps. It appears that you are using the multi-league standings shortcode. (??) As you can see, it’s working on this page https://dev.shoalsummitsolutions.com/multi-league-standings/.
But the error in this thread is in the BACK end, when trying to update standings. Which, btw, has nothing at all to do with updating the games.
So I would start by creating one brand new team and adding it to one brand new league. Then see if you can update the standings for that “mini-league”. Let me know what happens.
Another problem that frequently occurs, is that an admin deletes a team or league, but does not empty the trash. So the team or league is still in the database and if you create a new team or league using the same name(s) (actually the same slugs/permalinks), things get buggered up. So double check, empty any trash, and don’t re-use slugs/permalinks.
Let me know.
