not sure if the latest version have added the more path for backup..
"Try setting the $sqlpath variable in config.php to different paths, most common:
$sqlpath = '/usr/bin/';
$sqlpath = '/usr/local/bin/';
$sqlpath = '/usr/local/mysql/bin/'; "
If haven't, just add into it in future released, to make it more perfect for user that buy in future and having same problem :lol:
