 * I am trying to use this plugin for both a regular installation and a multisite
   installation of WordPress.
 * I’d love to use it, any advice on fixing these errors:
 * Stand-alone installation:
    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.
 * Multisite error:
    Warning: Creating default object from empty value in /home/
   marketsm/public_html/wp-content/plugins/jquery-color-picker/jquery-color-picker.
   php on line 101
