    I am receiving an error message of “WARNING: CANNOT MODIFY HEADER INFORMATION – HEADERS ALREADY SENT BY (OUTPUT STARTED AT” through out my wordpress website each time I use the php code within my page templates of header(‘location:’), example header(‘Location: http://demo.camavision.com/VCSWeb/‘). This code was working fine awhile ago, about a week ago to be exact. I tried shutting off all the plugins, updating the wordpress main source code, even tried going into the source code and fixing it but it just seems that a different line with same message of modify headers pops up… And another one… And another one… and etc. Getting WARNING: CANNOT MODIFY HEADER INFORMATION on multiple lines of the base code. As an example: “WARNING: CANNOT MODIFY HEADER INFORMATION – HEADERS ALREADY SENT BY (OUTPUT STARTED AT C:\WAMP64\WWW\VCSWEB\WP-INCLUDES\FORMATTING.PHP:5084)” Basically too many to fix for the source code, and all I do is just add a php code of header(‘Location: http://demo.camavision.com/VCSWeb/‘) in the template. It all comes down that the main source code from wordpress seems to either have a bunch of spaces or something wrong with the php <?php & ?> coding. Please fix….

    Did you modify any theme file?
    Did you try running the site all plugins deactivate?

    there might be some empty lines before of after <?php ?>

    I did not modify any of the theme files, and when I deactivated all the plugins, it is still having the same issue.

    We even noticed it happen when we updated the the theme from the last update. So after the update, the error started popping up.

    It will be difficult to diagnose the problem without looking at the files. theme is working fine on our local and remote servers.

    Change the theme to confirm the issue is with the theme. let me know. if possible mail me a temporary admin access details.
