 * Hi.
    I’m try to install your plugin on WP 3.4 BETA, but activation is giving 
   this error:
 * The plugin generated 636 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.
 * Any suggestion?

 * I have discovered that this plugin has issues on Windows based servers which 
   can cause the problem as you described above. I solved this by editing a line
   in the plugin – hopefully this fix can be included in the main plugin in the 
   near future. In the bootstrap\constants.php file on line 15 I changed:
    `define('
   PLUGIN_DIR' , substr( $dir, 0, strrpos( $dir, '/') + 1 ) );` to `define( 'PLUGIN_DIR',
   substr( $dir, 0, strrpos( $dir, DIRECTORY_SEPARATOR ) + 1 ) );`
