My blog is in a sub-directory. I created pages and I can get to those pages just fine when using a browser.
Using mobile browser takes me to the root level when I click on the page item.
ex: Blog is located at http://www.mysite.com/blog/. I have a page for specials so it's at http://www.mysite.com/blog/specials/. If I use wapple and click on "specials" on the site in my browser on my phone, I am taken to http://www.mysite.com/specials.
If I click on "specials" via browser on my PC, I am taken to http://www.mysite.com/blog/specials just fine.
