 * Hi Fruityoaty, we’re not able to reproduce on our end, and the code is correct
   there. Can you please post the exact errors you’re seeing?
 * Thanks!

 * Hi!
 * Just wanted to say I updated to version 1.4.4 today and this update has fixed
   the problems on my blog. Tested it a few times – the error messages have not 
   returned. THANK YOU!!!

 * just noticed we have the same issue — on wordpress 3.8
 * Updated some other plugins (Sucuri didn’t have an update available) and it seems
   to have gone away… odd…

 * Hello,
 * What’s the plugin version you are using? The old versions doesn’t have an update
   function but the new releases already have it. Make sure you are using the latest.
   You may need to disable this one and install the new.
 * Thanks,
 * Bruno

 * We were having some troubles debugging the plugin to prevent these issues, since
   most of the actions _(from older releases)_ were returning and printing data 
   at the same time. In newer releases we implemented a template system that is 
   working better and is helping us to avoid these annoying warnings.
