I found in wp-postspercat.php in the firsts lines
define( 'POSTS_PER_CAT_DIR', PLUGINDIR . '/' . dirname(plugin_basename(__FILE__)) );
i just it changed to
define( 'POSTS_PER_CAT_DIR', '/' . PLUGINDIR . '/' . dirname(plugin_basename(__FILE__)) );
And now, it’s ok and i can say again “What a wonderful job you did”
Thank you !!!!
