Support » Installing WordPress » error message – new wordpress site

  • Resolved Tikirolin84


    I just downloaded and installed wordpress, then I installed the Rumba theme. I want to start working on the site but I keep getting this error message no matter what I try to save, and also when I just try to visit the site.

    Warning: Cannot modify header information – headers already sent by (output started at /var/www/ in /var/www/ on line 1178

    Can someone help me? Google provided me with no answers.

  • Hi Tikirolin84,

    First and foremost, you want to test your site in a default state meaning all plugins need to be deactivated and your theme switched back to the one that came with WordPress (e.g., Twenty Fifteen or Fourteen will do). Then, if the issue fails to reproduce you’ve got a 3rd party integration bug. That said, just switch your theme back to Rambo and test again. If you reproduce the bug then, and no plugins have been activated, you can simply report your issue here:

    If, on the other hand, your theme behaves nicely and fails to reproduce the issue then reactivate one plugin at a time until you do reproduce the bug. Then deactivate all plugins except the suspect one and the theme. Once you know the combination of theme and plugin(s), then you can report your findings to both the theme’s author as well as the plugin(s)’.

    Hope this helps!



    just write <?php ob_start(); ?> on top of page /var/www/

    and on /var/www/

    Thank you to all.

    CMSHelpLive your answer fixed the error! Awesome!!!

    contact form 7 plugin Warning: Cannot modify header information – headers already sent by…

    I had the same problem with contact form 7.
    It was not possible to save the complete changes I made in a contact-form-7 form.

    when I clicked on save always the Warning above occours.

    I put

    <?php ob_start(); ?> on top of page on html/wp-includes/pluggable.php

    than it worked properly.

    Thank you CMSHelpLIve.
