I’ve just run into this issue as well. I wish the author of the plugin would have a look at this and fix it. * Wouldn’t it be great if we could register issues directly on the plugin? Drupal has that. So the number of open and closed issues and bugs can help you decide whether you want to look into using this plugin. * [lyj_e1](https://wordpress.org/support/users/lyj_e1/) * (@lyj_e1) * [14 years ago](https://wordpress.org/support/topic/plugin-feedwordpress-feedwordpress-error-warningcannot-modify-header-information/#post-2551660) * Hi, * Had the same error on 3.3.2, Tosaha’s fix resolved the issue.

I’ve incorporated a similar fix already into the Development Version of FeedWordPress, which should be part of the next public release.
