ERROR When about to add matches

This will be fixed in a new release that I’ll put out shortly, but if you want to fix it on your own, change this (starting on line 99 of match.php in the admin folder):

//$match_day = 1;
$matches[0]->year = ( isset($_GET['season']) && is_numeric($_GET['season']) ) ? (int)$_GET['season'] : date("Y");

to

//$match_day = 1;
$matches[] = new stdClass();
$matches[0]->year = ( isset($_GET['season']) && is_numeric($_GET['season']) ) ? (int)$_GET['season'] : date("Y");

So you are adding:
$matches[] = new stdClass();

to line 99.

Then replace this (starting on line 104 – after the above change – of match.php in the admin folder):

for ( $h = 0; $h < $max_matches; $h++ ) {
	$matches[$h]->hour = $league->default_match_start_time['hour'];
	$matches[$h]->minutes = $league->default_match_start_time['minutes'];
}

with this:

for ( $h = 0; $h < $max_matches; $h++ ) {
	$matches[] = new stdClass();
	$matches[$h]->hour = $league->default_match_start_time['hour'];
	$matches[$h]->minutes = $league->default_match_start_time['minutes'];
}

which adds the same text to line 105
