[Plugin:Contact form 7]

Hi! I am using contact form 7 (version 3.8.1) and I can’t make the “successfully sent” message appear (or any other message). I researched about this topic, but everything I found were posts from 3 years ago, so they were using older versions and it didn’t help me. I would like to know if there is any possibility to make it work, or which alternatives I have to this free plugin.

Thank you
