Hi All,

I’m having trouble getting action\_profiler (http://rails-  
[analyzer.rubyforge.org/action\_profiler/](http://analyzer.rubyforge.org/action_profiler/)) running on my app. I am  
running on Rails 1.2.2, and am using ActiveRecordStore to store my  
sessions. I’ve included the dump below…

Thanks in advance.  
Mark
