Headers' Sent Traceback

    Am in the ‘Headers Sent’ Hell!

    On redirect my code shows that headers were previously sent from headers.php line xx. More to the point when I cut a new page including the following text
    <?php print_r(headers_list(); headers_sent ($file ,$line);echo $file ,$line; ?>
    , it shows that headers were sent from headers.php same line.

    I have:
    – checked for errant spaces/stuff in headers.php, wp-config and of course my code.
    – used alternative theme
    – reinstalled suffusion
    – disabled all plugins, bar exec php
    – done a wp4.1 upgrade
    All to no avail. Worse on another similar site, headers_sent shows false. I have compared wp settings and, apart from there being no ‘default link category’ on write page, they are identical.

    I have done a trackback on the headers.php function call (below) and in my ignorance I don’t know whether that shows a normal course of events, or whether it points to a source of the problem

    Please could someone rescue me from my stupidity?

    I have solved this and I think I understand why.

    I am stupid!

    I am doing redirect in php code executed within wordpress page. It seems that headers have already been sent in this situation. On my development site, where I didn’t get ‘header sent’ I had enabled ‘WP Fastest Cache. On the operational Site I hadn’t. When I enabled it the problem went. Presumably the cache prog adds in that stuff later.

    (mind you when I tried the same with a different cache program the problem remained; maybe a different approach.)
