Thank you for the answer.

In any case, with the default plugin, never validates if the file field is required or it has reached the limit of file size.

It is very weird, because it works well in other webs.

Could be any setting of the server the origin of the problem?

Thanks.

Open plugin folder/includes/process.php

look for line 145 to line 146

$tax_query = isset($get_tax) && empty($keyword) ? 	$get_tax : null;
$meta_query = isset($get_meta) && empty($keyword) ? $get_meta : null;

change to

$tax_query = isset($get_tax)  ? $get_tax : null;
$meta_query = isset($get_meta) ? $get_meta : null;

I test this, and it works very nice!
