start Private message

I’m having trouble associating/connecting the user from the single user “private message” button page. When the button is clicked, it is directed only to the account page, and does not start the message with the profile user. I don’t have much knowledge of code, if you can help me as clearly as possible I would appreciate it. (For the record, I’m using the Crocoblock plugins/jetplugins to create members/posts/single users) I added these codes inside wpcode PHP Snippet.
