 * > The plugin generated 174 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 ideas? Thanks…

 * You can safely ignore the error. It’s only an issue on activation and doesn’t
   affect ongoing performance.
 * I’m not sure what’s going on here. It’s a known issue, but it seems to be a problem
   with WordPress rather than the plugin, as strange as that sounds. I haven’t looked
   into it in real detail yet. Somehow the file is included twice and one function
   is therefore declared twice.
