If I subscribe to newsletter on e.g. www.example.de/en/subscription.html, I get the email for confirming my subscription. The link in the email contains the /en/-path as well (www.exampe.de/en/?tx_pxanewslettersubscription_subscription%5Baction%5D=confirm&tx_pxanewslettersubscription_subscription%5BceUid%5D=4419&tx_pxanewslettersubscription_subscription%5Bcontroller%5D=NewsletterSubscription&tx_pxanewslettersubscription_subscription%5Bhash%5D=0f2b6cd5c11af3718ea086e0d8361ba143e9d0b1&tx_pxanewslettersubscription_subscription%5Bsubscription%5D=3832&cHash=795889511ab3178615d16dc1a57fbc4c). But when I click that link, the plugin gives an unknown error: "Sorry, something went wrong. Please contact us." I guess, the problem concerns to the path component /en/.
