Thanks for the great plugin.
But after installation there was a problem.
If you enable the option: "Auto merge double posts", then when you try to post a second comment, the error "The requested resource was not found." If you click "send comment" 3 times, the error will appear 3 times, but if you reload the page after that, then this comment will be displayed the same way 3 times.
What could be the problem?
