[Solved] Page reloads twice during subscription or unsubscribe

Hi!

I'm new to this plugin. Is it normal that page is reloading twice while subscribing or unsubscribing?

For instance, when user clicks subscription button, page reloads with such URL parameter:

?wpdiscuzUrlAnchor&subscriptionSuccess=1&subscriptionID=XX#wc_unsubscribe_message

Then it reloads to original URL.

When user clicks unsubscribe button, page reloads with such URL parameter:

?wpdiscuzUrlAnchor&wpdiscuzSubscribeID=XX&key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX#wc_unsubscribe_message

Should this work this way or should some kind of Ajax function be used? If second, how reloading page can be prevented and fixed?
