[[function.array-key-exists] after upgrade to php7

I just changed to php7 base on recommendation on wordpress dashboard.
now im getting these 2 messages on the top of wordpress dashboard:

[function.array-key-exists]: The second argument should be either an array or an object in /home4/fitxcana/public_html/wp-content/plugins/leadin/admin/leadin-admin.php on line 79

The line shows (starting line 79):
if (!array_key_exists(‘li_grant_access_to_’ . leadin_get_user_role(), $options))
return FALSE;
else {
if (current_user_can(‘manage_network’)) // super admin
$capability = ‘manage_network’;
else if (current_user_can(‘edit_pages’)) // editor
$capability = ‘edit_pages’;
else if (current_user_can(‘publish_posts’)) // author
$capability = ‘publish_posts’;
else if (current_user_can(‘edit_posts’)) // contributor
$capability = ‘edit_posts’;
else if (current_user_can(‘read’)) // subscriber
$capability = ‘read’;
