hi and welcome to daniweb. Next time please start a new topic instead of bumping a really old topic. As for the problem, there is probably a bug in your query. So try replacing line 201 and 202 with the following

$query = mysql_query($sql) or die(mysql_error()); 
$nume = mysql_num_rows($query); // --> line 202

I checked an article and it appears that the problem is with the way mysql is operating. It is like if there is something wrong with the mysql temp files located in your /tmp/ directory. If this is wamp or xampp then I would suggest rebooting the mysql service and if that doesn't work then perhaps a google search on "mysql error code 28" might give you a better picture.
