Many users have asked us why updating settings under OptimizePress > Global Settings, such as a logo or header colors does not change existing pages.
The Global Settings options are designed to be used when setting up a page for the first time if you are using the Blank Template when using the Page Builder.
Once a page is created, in order to change the header, you must launch the live editor for that page and then go to Layout Settings > Header & Navigation in order to select different options.
We realize that this may not be the best solution and are currently exploring some options to make it easier to design and redesign headers.
