I just scanned through the log and didn't see any direct reference to a 500 error. The 'regular' site is working fine - and I get no error on my iphone, just a blank white screen. In fact, even the site title is just 'untitled'. Like it's not reading the template at all. I haven't made any changes to the default settings (which worked in 0.9.9) except to point to the correct menu in the iphone header. If you can give me some further guidance, I have access to our server, but I didn't even see where the system was serving the new pages at all.
