WP-DBManager version 2.50 .after Active the plugins ,AdminPanel always received : WP-DBManager 2.50 安装激活后，控制台总是收到如下错误警告:

"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/username/commondork.com/wp-content/backup-db"

There is not a such file named .htaccess in /wp-content/plugins/wp-dbmanager. But Its easy. 但其时插件目录中没有.htaccess文件。经过论坛讨论和考证。最终解决办法如下。

Create one file named .htaccess in than upload to the backup-db directory(Use filezilla can upload file named . xxx )

or

Go to wp-content/plugins/wp-dbmanager find a file named htaccess.txt. then rename it to .htaccess and move it to the backup-db directory.
