A notification about file owner appears along with an FTP form, how can I resolve this?

The plugin uses PHP functionality to write to files, it cannot write or modify files it will give you a warning. Typically, you should tell your web host about the permission issue and they should be able to resolve it.

You can however try adding define(‘FS_METHOD’, ‘direct’); to wp-config.php to circumvent the file and folder checks. See this for more information of setting up file and folder permissions for WP
