Hi,
I created a child theme. I inserted your “categories” widget into a page. Everything works fine except that when I select one category, the archive posts page that pops up (in my case: http://portfolio-resolution.de/category/allgemein/) is not full width. I did remove the sidebars in appearance settings but still the page is not full width.
What can I do?
Are you using our theme? If so, that is actually the template it displays archive pages. We can use custom CSS to make it full width, but it seems your site is in maintenance mode. Can you either take that off, or grant us access so we can check and provide the necessary code?
