 * When I click test or update integration I get this error message:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /mhpattern/wp-admin/includes/template.php:2532) in mhpattern/wp-includes/pluggable.
   php on line 1340
 * Do you know what is causing that error? How can I fix it?
 * Thanks,
    Anders
