Just received this from support :
The problem you’re experiencing is because we have upgraded Rails, and
apparently it’s affecting your setup, most likely because you didn’t
freeze your apps. We announced this upgrade on the 15th:
I tested it and got this error:
pepsi: 01:18 PM# ./dispatch.fcgi
Cannot find gem for Rails =1.1.6:
Install the missing gem with ‘gem install -v=1.1.6 rails’, or
change environment.rb to define RAILS_GEM_VERSION with your desired
According to our admin who handled the upgrades, in some cases, changing
the variable RAIL_GEM_VERSION to 1.2.3 (the latest) in your
config/environment.rb file will fix a broken install. In other cases
reinstall will be needed."
Changing the variable worked for me.
I don’t think that a posting on the status page is really the best way to warn people that their sites might go tits up. It’s not like I regularly read the status just to see if they’re gonna fiddle with my site. But at least I’m up and running again.
