After setting up the forum name, database, and forum administrator, the forum goes blank white saying something went wrong, and go to the next page, which is a blank page. I am running Apache2, Ubuntu 16.04 TLS, as I have configured the web server block correctly, I have set the correct permissions, and I have installed all needed php and apache2 modules and extensions. It is currently installed in the root of apache2. I have tried Nginx, and Apache2.
(EDIT)
Error...
