I'm working to set up a new blog, and am having a hard time because when I do anything (even add or deactivate widgets, etc), I get the following message:
Warning: Cannot modify header information - headers already sent by (output started at /homepages/2/d222657943/htdocs/bentofun.net/wp-content/plugins/wptwitter/wptwitter.php:281) in /homepages/2/d222657943/htdocs/bentofun.net/wp-includes/pluggable.php on line 865
The "pluggable.php" file is different every time. There have been several different files documented, but the warning about "cannot modify header information" is always the same.
Any thoughts on how to fix this infuriating error?
