Just a guess but this plugin uses PHP sessions so that might be the cause.
Otherwise, these are the only two places I can see that modify headers within the plugin:
The first has a conditional so should only happen on ?csv=1 (exporting csv?)
The second should only happen when exporting settings.
Hey m8,
as soon as I activate your plugin "Send PDF for Contact Form 7" it prevents my Varnish or W3 Total Cache from caching. I investigated it further and found out, that somehow your plugin adds no-cache header to http-response.
Could you tell me why this is the case and how to prevent this? Otherwise I won't get my Varnish working properly.^^
Thank you!

How to reproduce: Simply set up a default WordPress with "Send PDF for Contact Form 7" plugin and load frontend.
