I am getting the following error:

/!\ FAILSAFE /!\ Tue May 06 08:32:25 -0500 2008  
Status: 500 Internal Server Error  
wrong number of arguments (2 for 0)

I looked at the controller code and I am not using ruby send command  
or anything that looks like code that redefine rails method. The error  
message does not really help in pointing where the problem occurs. Any  
ideas on how to debug this? Thanks

Quick guess: do you have an action called process ?

Yes, I did have an action called process. Thank you Fred!! I couldn’t  
figure out what was causing such a weird error. Renaming the action  
from “process” to “process\_login” fixed the problem.

Please disregard this posting. I found the issue. I had a method  
called “process” in my controller which I guess is causing the  
confusion. I changed it to “lprocess” and that fixed the issue.
