I purchased the Kanso theme and imported your dummy content that was included. On top of that, I imported content from an old website that I am re-designing for a client, so I have many pages in WordPress.
I have set up the One-Page site per the documentation included (you can see the site here: http://spas.future-farm.com/demo/combined/) but cannot seem to get any of the pages to be excluded from this One-Page template.
You can see that in the Theme Options I have declared only three pages to be included (http://i.imgur.com/qMjT1Jg.png), but the site is not changing accordingly.
If I could get any insight into how to fix this issue I would be very grateful.
This is a known issue, and it has been corrected in the upcoming 1.5 version of the theme; the new version is still being checked by ThemeForest staff before it goes live, yet here is the file that contains the fixed code. Please unzip the archive and upload the resulting file into the theme folder (/wp-content/themes/Kanso/), replacing the existing file. Please let me know if this helps remove the bug!
