False error that the theme is missing

Hello,

As soon as I install the theme, I get the false error User warning: The following theme is missing from the file system: personal_portfolio_and_blogger_theme. For information about how to fix this, see the documentation page. in _drupal_trigger_error_with_delayed_logging() (line 1138 of /var/www/drupal-7/includes/bootstrap.inc). When I say false, I mean false because I have never even heard of personal_portfolio_and_blogger_theme, let alone install it.
