Hello Nat,

I'm sorry but I can't replicate in my local. Can you provide us a screenshot of the notice? By the way, after I've made quick research, it seems like it is came from Joomla. If you Google it, you will find a lot of discussion about this issue. You might want to give it a try.

thank you Mohd! it seems to have rectified itself??!

Thanks for updating Nat. That message is probably because one of your email recipients has an invalid email address but it should only be seen once because it would not be processed any longer (provided that the email came from EasyBlog). It could come from somewhere else too.
