Themes breaking clean install

Hello,

I am new to Typo and just performed a clean install. Everything works
fine
when using the Azure theme, but when I switch to another theme (I have
tried
Hemingway and Scribbish) I get an error when attempting to load my blog.
No
problem activating the theme in the control panel, the error only occurs
when I leave the admin area. The error varies by theme; I am wondering
if
maybe themes are broken or if I am doing something wrong: any help would
be
appreciated. Apologies in advance for my lack of RoR knowledge: sorry I
can’t figure this one out myself. Thanks!
