I'm getting the following error with Twitter For WordPress:
Warning: Cannot modify header information - headers already sent by (output started at /home/id05404/domains/metspuug.nl/public_html/wp-content/plugins/twitter-for-wordpress/twitter.php:1) in /home/id05404/domains/metspuug.nl/public_html/wp-includes/pluggable.php on line 850
I get this error ever since I edited the line 'No Public Twitter Messages' into 'Twitter doet poep.'. But that shouldn't be a problem since it's just an echo... I only get this error in the admin, and even though I get this error it does the action (like adding a post or updating a widget).
How can I fix this?
