This started because I logged into my computer at 8:00 A.M. Tuesday, April 21, 2015.
I started setting up our daily emails and needed a good quote for SITE1's email.
I went to the site - it was down. That's weird. I was getting a 500 Internal Server Error - big problem.
The Outreach theme (which SITE1 uses) relies on a file called header.php.
