I have been trying to change/update the masterpage, I have some requirements to rebrand our front page. I have saved a copy in SP Designer, Seattlecopy2.html, edited the script there, clicked save and refresh but when I click preview in browser the changes do not show up.
I mean even basic changes like changing the ribbonrow color. I'm testing on SP 2013 using SharePoint Designer.
Any help would be greatly appreciated.
