ERROR – Your backup folder MIGHT be visible to the public

Just upgraded to 3.8 wordpress and Version 2.65 of the WP-DBManager

I now cannot remove the error message:
——————————
Your backup folder MIGHT be visible to the public

To correct this issue, move the .htaccess file from wp-content/plugins/wp-dbmanager to /home/ec2-user/html/wp-content/backup-db
——————————

There is a .htaccess file present (see below)

$ pwd
/home/ec2-user/html/wp-content/backup-db
$ ls -latr
total 12
-rw-r–r– 1 ec2-user ec2-user 58 Jan 14 2012 .htaccess
drwxr-xr-x 9 ec2-user ec2-user 4096 Oct 30 19:51 ..
drwxrwxrwx 2 ec2-user ec2-user 4096 Jan 8 12:27 .

——————————

And it does contain the following

——————————
$ cat .htaccess
<Files ~ “.*\..*”>
order allow,deny
deny from all
$
——————————

I have searched for answer on wordpress and here in support forum, but am confused why I now see this error message?

thanks

Mark
