I am trying to build a championship, but the problem is I can`t seem to add matches. I have created a League, edited the preferences (mode-championship, groups-A;B;C;D etc.), added the teams and assigned them to groups. But when I try to add matches I get the following error:
Warning: Invalid argument supplied for foreach() in /wp-content/plugins/leaguemanager/admin/show-league.php on line 22
I have also tried to add a season, but I get the same error...
