 * Hello. I cannot log into my site lately and this is the error message I keep 
   receiving:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/content/53/10485253/html/wp-content/plugins/quttera-web-malware-scanner/
   qtrScanLock.php:79) in /home/content/53/10485253/html/wp-login.php on line 387
 * After googling this message, I’m finding that most people suggest disabling plugins.
   I would try this, however I cannot get past the login page to access anything
   to do with my site. Can someone please help me with this?

 * delete “quttera-web-malware-scanner” plugin using [FTP ](http://codex.wordpress.org/FTP_Clients),
   or your web-host’s cPanel or whatever file management application your host provides(
   no Dashboard access required).
