Client PDF Display Issue Wordpress

I’ve been wracking my brain over this one and cannot find an answer anywhere – so can anyone help?

I have a Wordpress site set-up for a client. They want to be able to upload PDFs and Word docs, display the link on a page, allowing people to download them. All OK so far.

I tested it on my computer and no problem, works fine. But everytime they try it they get the “headers already sent” problem. I tried it on their PC and sometimes it works, most times it doesn’t.

My only thoughts are that it could be something to do with their version of Word or something obvious I’m missing.

Any ideas?

Try adding

At the beginning of the page where you are getting this error, hopefully this will solve the problem.

Thanks Dhruv. I’ll try it.
