    When saving Wiki Settings receive error 'Cannot modify header information'

    Just like the issue stated here: http://premium.wpmudev.org/forums/topic/wiki-error#post-98038

    Wwhen I try save Wiki Settings [slug] the following error appears...

    Warning: Cannot modify header information - headers already sent by (output started at /PATH/wp-admin/admin-header.php:35) in /PATH/wp-includes/pluggable.php on line 897

    I tried checking for, and removing, any trailing whitespace from the mentioned files and from the wp-config.php, but that didn't resolve the issue.

    Oh, I also disabled all plugins except Wiki [Lite]. Still receiving the error.

    Hiya Eric,

    Maybe try deleting the plugin and re-uploading a fresh download?

    I just downloaded a copy and put it on an install and wasn't able to replicate this.

    Sometimes things don't get uploaded/copied correctly - a new download would help clear that up.
