Cannot Modify Headers Error with Content Copier

I haven't noticed a problem with the plugin fuctioning yet, but my debug.log is giving me this error over and over and over again.

[05-Jan-2016 16:55:44 UTC] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/travsear/public_html/wp-content/plugins/multisite-content-copier/multisite-content-copier.php:114) in /home/travsear/public_html/wp-includes/option.php on line 820

Not sure how to fix it.

Thanks
