 * Errors:
 * ( ! ) Notice: is_author was called **incorrectly**. Conditional query tags do
   not work before the query is run. Before then, they always return false. Please
   see [Debugging in WordPress](https://codex.wordpress.org/Debugging_in_WordPress)
   for more information. (This message was added in version 3.1.0.) in /app/public/
   wp-includes/functions.php on line 4147
 * ( ! ) Warning: Cannot modify header information – headers already sent by (output
   started at /app/public/wp-includes/functions.php:4147) in /app/public/wp-admin/
   includes/misc.php on line 1114
 * When working with [https://wordpress.org/plugins/co-authors-plus/](https://wordpress.org/plugins/co-authors-plus/)
 * Works fine with Version 2.3.5 of SW.

 * p.s. We are a premium paying user. We have resolved this by downgrading to 2.3.5
   but this is not ideal. Let me know if you require further information from us.
   Problem seems to be SW calling is_author method before headers sent.
