I have changed some header template code and when I save the header and make it live it appears to take. When I go to the main page of our site on that computer everything looks fine. Hours later on another computer I noticed the site had not changed yet. I went into the template editor and sure enough the changes were back to the way they were before I made the changes, I thought. When I went back to the original computer, the header changes were shown, so effectively I have two computers that can edit the same header template that show different code? How the heck is that happening?
