I found a solution, however is not the best solution because you need to change the core.
Follow my solution after read php_erro.log.
Important: Create a backup of this file before change. Do at first in development environment before change in production.
Go to /libraries/cck/base/list/list_inc.php
In error log, showed me some problems in this file in 3 lines.
Line 135
$variation = explode( '||', $variation);
change to
$variation = explode( '||', $variation ?? '');
Line 459
$total = count( $items );
change to
$total = count( (array)$items );
Line 743
$config['validation'] = ( count( $config['validation'] ) ) ? implode( ',', $config['validation'] ) : '';
change to
$config['validation'] = ( count( (array)$config['validation'] ) ) ? implode( ',', $config['validation'] ) : '';

Remember this solution is not the best. You have to change this until Seblod Staff fix this in forward versions.
