Modifying Edit Profile Page

Hello,

I’m trying to modify the edit profile page. I commented out the includes for the admin header and footer. This results in an unstyled edit profile page. When I try to add my own HTML, the page renders, but when I try to submit the form it says something about “headers already sent.”

I read that this usually happens when there’s space before <?php but there is no space in front of it.

Any ideas?

Thanks.
