I switched from using the filesystem to active_record_store for session
and some users of my site started getting this error:
Change this error message for exceptions thrown outside of an action
(like in Dispatcher setups or broken Ruby code) in public/500.htm
Here is the weird part. This only happens for some users and once a
user gets this error they will continue getting it on every page they
try to go to. If they delete their cookie, i.e. get a new session, they
can browse the site again. But, once they get the error again they'll
have it on every page. If i switch the sessions back to the fs all is
fine. Go back to active_record_store and it happens again.
The worst part is that there is NOTHING in the log files. Anyone have
any ideas of what could be wrong or at least how I can get a stack
trace or a log of the error.
