Can someone please help me with this? My knowledge is far too limited in this area.
I ran a scan with the Sucuri Security - Auditing, Malware Scanner and Hardening plugin and received a "PHP Error: Headers already sent" message. So I went to the Sucuri SiteCheck site and ran a scan and it cam back with this:
