Site somehow picked up a Trojan Iframer over the weekend. Silly me had not created a site backup. DOH!! So, FTP downloaded everything from the root and ran it through a find and replace with a little free app called Text Crawler to remove the malicious code. Everything is clean now and uploaded back to root.
However the homepage now shows this at the top of the screen.
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/12/5094712/html/wp-load.php:2) in /home/content/12/5094712/html/wp-content/plugins/wordpress-newsletter/newsletter.php on line 29
I tried deleting the newsletter plugin via FTP, but no luck.
