Installing CI4 app on Plesk

Hello dear CodeIgniter community,
I'm having a hard time right now trying to get my application running on ubuntu 18 with plesk installed.

Everything works fine on local with spark, but i can't figure out how to get it running on my webserver.

I followed the deployment tutorial on the wiki but it did not help me that much.


I really hope you guys can help me   
(yes im still nooby in programming)

Thank you

I actually got it to run
My Problem is now that the url looks like <domainname>/public/stuff
How do i get rid of /public?
