Rails app starts but Errors

Question

My Rails app starts but gives me a No Method error. I'm not sure what method is apparently being called on something which doesn't. It can;t be a certain site page as it's happening on every url I try to visit. Anyone able hint where it's failing?

I'm sure you quite beyond this but just to chime in, I had the same error. I commented out the better_errors gem, re-bundled, reran my app, and found I was getting an error elsewhere. I don't know why better_errors was unable to handle it but once I fixed that other error, I re-enabled better_errors and everything was back to normal.

It's odd b/c I haven't had any problems with the gem before. I love it.
