 * When activating this plugin, I get this error message:
 * > The plugin generated 2 characters of unexpected output during activation. If
   > you notice “headers already sent” messages, problems with syndication feeds
   > or other issues, try deactivating or removing this plugin.
 * Yes, the plugin still functions, but it creates a problem logging out of WordPress
   and returns me to a blank white screen.

 * Thanks Polyfade,
 * This should be fixed in the latest version I just added (1.1.0).
 * The error was due to extra blank lines at the end of the main PHP file, which
   I’ve now removed.
 * Thanks for the heads up, and let me know if you’re still having trouble!
    – Mickey
 * PS – I believe this error only occurs if you have debug mode turned on in wp-
   config.php.
