Too many redirects

Greetings – I’m getting a “Too many redirects occurred trying to open
“http:///forum/” when going to the top domain of my site.
/user/login work fine.

BTW, when I originally edited site.rb, I’ve enclosed ActionMailer
settings to :smtp in if RAILS_ENV != ‘test’ – that was giving an error,
RForum::RAILS_ENV undefned; then site.rb wouldn’t load properly and
default_site was loaded instead! I guess that needs better exception
management to expose syntax errors in site.rb.
