I like the premise behind the Upfront themes, but I've been disappointed by what appear to be implementation issues (not sure if it is from my input or shortcomings in the design).
I created a very basic framework of a site for a client (arcobuilders.nettechdataservices.com) using the WordPress TwentyFifteen template. I added a few pages (Contact Us, Our Approach, Home, etc.), pasting in content from their existing live site. When I applied themes based on Upfront (first trying Fixer, then switching to Spirit), I expected the pages to be converted to pages in the menus of the theme. Instead, I see the theme's default pages linked through the menu, and all the pages I created are completely disconnected from anywhere in the site. The theme seems to have been applied to the content, but on the Clients page I created which contains a large table with all their client history, I see a notice that Custom Sidebars are "Not available for blog pages". Why that was created as a blog page, I'm not sure. But it does show a "Report this Post" link at the bottom, despite having only been a simple page upon initial creation.
Did I do something wrong? Should I have set up my menus before switching themes (and would doing so have reflected my own menus rather than theme defaults)?
