Comment (by dd32):

 Hi @thirst4beats,

 This is indeed a plugin issue, and not core's, and is unrelated to the
 update you performed, It's likely that the plugin was updated at the same
 time as you did the core update, which would explain why it only appeared
 at that time.

 The plugin in question as shown in the error is this one:
 {{{
 /home/thirst4beats/public_html/wp-content/plugins/wpheadsp/wpheadsp.php
 }}}

 As it's starting output at line 1, it's most likely an empty line before
 `<?php` or another invisible character before it. I'd suggest removing the
 first line of the file and re-writing it.
 I can't find any plugins by that name, so I'm not sure what it is - but if
 it doesn't disable through the plugins page, you can rename the folder to
 check it's cause.
