Hi,

When I go to my homepage all is well, however when the Pingdom bot  
arrives (every few seconds!), it throws the following error:

ActionController::RenderError occurred in home#index:

You called render with invalid options : available  
[RAILS\_ROOT]/vendor/rails/actionpack/lib/action\_controller/base.rb:808:in  
`render\_with\_no\_layout’

My index action doesn’t call render, it just renders the index.rhtml  
file as per normal.

These are the headers I get when pingdom comes to my site: I get these  
sent to me every few seconds.

Anybody any ideas?

Pingdom sends this param item. I’m guessing you must be trying to  
render the text “available” somewhere instead of rendering  
index.rhtml… that’s what Pingdom asks for in a response as I recall.  
Maybe you have this in a before filter instead of the index action?

Yeah - you’re so right. I rendered “available” when a subdomain was  
available to register (in my app) … still left overs from the  
‘prototype’. I now render a 403.html page with a 403 status. Thanks.
