This is the first time this has happened to me on two separate websites that I have installed a clean version of J3.36 and a demo installer of Central and Alexis. When I try to modify the default template by either something simple as turning the logo off or setting a different example style to default it does not show the changes on the live site. I have tried clearing the cache, restarting the browser and logging out. It is probably some default setting in the config that I am not seeing..
