running on macbook pro 10.9.5, except for Config+discussion

Interesting. Are you getting anything in the log ( [deck root]/log/production.log )?

Here's what the page is supposed to look like: http://template.decko.org/Config

I wonder if any given card nested in that page would hang. Like *all?

just to be sure, i created, seeded, and started server on a new site and the first thing i did was click on Config. It hung. here is the tail of the log:

===

Started GET "/" for ::1 at 2015-08-24 19:36:18 -0700

Processing by CardController#read as HTML

Rendered text template (0.0ms)

Completed 200 OK in 133ms (Views: 0.4ms | ActiveRecord: 7.9ms)

Started GET "/Config" for ::1 at 2015-08-24 19:36:24 -0700

Processing by CardController#read as HTML

Parameters: {"id"=>"Config"}

Completed 500 Internal Server Error in 528ms (ActiveRecord: 17.6ms)

SystemStackError (stack level too deep):

activerecord (4.2.4) lib/active_record/connection_adapters/abstract/connection_pool.rb:661

===

It's a repeatable error.

I've been trying and failing to reproduce this on my own macbook pro.

The "stack level too deep" doesn't tell us much. Is there any chance you'd be willing to create a file named "config/environments/production.rb" with the following content:

Wagn.application.class.configure do
  config.log_level = :debug
end

....and see if it tells us anything more helpful in the logs?
