My blog is http://www.carlosmiller.com and lately when I try to activate a plug-in, I get the following message and I have no idea what it means.
I thought this would be fixed if I upgraded, but I upgraded and I still have the same issue. The message is:
Warning: Cannot modify header information - headers already sent by (output started at /home/magic64/public_html/carlosmiller/wp-admin/admin.php:114) in /home/magic64/public_html/carlosmiller/wp-includes/pluggable.php on line 390
