Password reset triggers "MethodNotAllowedHttpException"

Hi Guys,

I am getting a weird error on the production server. On the development server, everything works smoothly.

The problem is related to Spark's Password Reset feature. When I enter an email address and hit the "Send Password Reset Link" button;

(1) On development server, it sends the password reset email and displays a success email.

(2) On production server, I simply get this:

MethodNotAllowedHttpException in RouteCollection.php line 218:

at Kernel->handle(object(Request)) in index.php line 54

Everything is same on both production and development servers. What can be wrong? Any suggestions?

Thanks.
