I cant get the attachment working, my error log says this:
wpMandrill::processAttachments: Array => Error creating the attachment structure: Array is not a valid file. wpMandrill::sendEmail: Exception Caught => Invalid attachment (check http://eepurl.com/nXMa1 for supported file types).
The shortlink URL for supported files does not give any useful information.
My array looks like this, very simple just for test.
Array (  => Array ( [type] => text/plain [name] => Test.txt [content] => VGVzdGFyLi4u ) )
What am I doing wrong? Im using WordPress 3.8.3 release with plugin up-to-date.
Thanks in advance.
