wordpress headers already sent problem

I am getting reports that some users are getting an issue when trying to access a client's homepage. I cannot reproduce the error on my PC, but they have sent me screen shots.

i have attached the screen shot below.

pluggable.php is the WP core functions which can be overridden by a plugin. Does that site have plugins installed which would be immediately active for some users and not others?

the only plugin that i think is immediately active on the homepage is easing slider. I am going to put in a question to the tech support there because i have that on 2 sites that have provided similar issues.

the URL in question is www.cornerstoneshiloh.org

Try disabling the slider (replace with a static image) and see if the messages stop?

yeah, anticipated that and tried i with no luck.

Worst part about it is that i am not duplicating the error on my end so it makes it very difficult to troubleshoot.

Hmm.

It's possible, albeit unlikely, that a firewall or proxy is in play and causing duplicate requests to be made of the WordPress site. This could result in a "headers already sent" for those users and not others. Good luck proving it, though.

Doesn't seem to be confined to a specific network at all. Any ideas why it would show fine for some and not all?

none of the other comments led to the answer. We found the problem to be a much bigger problem than originally anticipated.
