Problem with permissions in wp-content/plugins

Best thing to do is check the WP docs themselves for correct file/folder permissions and how to change them, if needed: http://codex.wordpress.org/Changing_File_Permissions

Typically, all files should be owned by your user (ftp) account on
your web server, and should be writable by that account. On shared
hosts, files should never be owned by the web server process itself
(sometimes this is www, or apache, or nobody user).

Is “tape” a local user name? Or FTP name?

Depending on what kind of system you’re using – a local install of apache, php and mysql – or a stack like Bitnami, XAMPP or MAMP, there may be slightly different owners and groups for folders and users.
