Headers already sent error

  • Hi, I enabled Document Repository on a single blog in a Multisite install (subdirectory).

    When I go to view an uploaded document, I get this error:

    Warning: Cannot modify header information - headers already sent in /home/directory/public_html/wp-content/plugins/document-repository/document-repository.php on line 300

    I’ve looked at the code and don’t see any particular reason why we’d be getting this. Any ideas? thanks.

    FYI: I created a new site in our Multisite and switched to the TwentyEleven theme and I still get the errors.

    My first guess would be you have a blank line at the end of a plugin file (or the theme’s functions.php).

    Thanks. It’s not the theme, since I still have the problem when switching themes. I will look at the must-use and network-enabled plugins.

    I don’t have a good explanation for it. But, exempting the URL from WP Super Cache (so it’s not cached) seems to have solved the problem.

    Super Cache is probably adding headers in advance of the document being loaded.
