Cannot modify header information

Hello. Love your plugin, but your recent update from 3.64 to 3.65 seems to have broken my site. I am getting the following error:

Warning: Cannot modify header information – headers already sent by (output started at /home/customer/www/mysite.com/public_html/wp-content/plugins/code-snippets/code-snippets.php:1) in /home/customer/www/mysite.com/public_html/wp-login.php on line 504

Is this something I can do to fix this on my end or is there an error in your code that needs to be patched? I will revert back to v 3.64 until I hear back from you guys. Thank you!
