How to disable the Page-Sidebar in Marketpress?
The Main-Market-Page has the full-width-page setup, but all other sub-pages ignore this setting and uses the default-page setting.
How to define that this "invisible" sub-pages also use full-width-page
I dont use a Marketpress theme, I use the workality theme which I customized for my whole wordpress site. This theme features all full-width pages among others, but as I mentioned, marketpress falls back to the default-page setting which features a Page-Sidebar.
