Question

I am getting an error like this

Exception Traces:

---

 --> stack level too deep

 --> /var/www/html/mysite.com/mysiteweb/mysite/vendor/plugins/authlogic/lib/authlogic/acts_as_authentic/base.rb:86:in `include?'
 --> /var/www/html/mysite.com/mysiteweb/mysite/vendor/plugins/authlogic/lib/authlogic/acts_as_authentic/base.rb:86:in `first_column_to_exist'
 --> /var/www/html/mysite.com/mysiteweb/mysite/vendor/plugins/authlogic/lib/authlogic/acts_as_authentic/base.rb:86:in `each'

Not sure why this is happening. Searched a lot and found that many has got this error. But not sure why this is happening.

My authlogic plugin version 2.1.6

I get this same error in different scenarios

Can anyone please explain the root cause of this issue. I am not able to figure it out, what exactly is the cause for this.

Answer 1

You get this exception when there's infinite recursion, most likely. You should check your code for that.
