Trying to install OJS 3.1.1.2. Everything is fine until I want to press the button install. The 500 error shows and in the error log this shows (picture below). I have tried to figure what could be wrong in apache2.conf but with no success. It might be something else completely.
Thank you for your help!

Hi @Jernej_Rejc
Are you using git to install or a tarball? It seems that your Apache server can’t handle the installation.
Have you check PHP error log or enable DEBUG options in config.inc.php
Best,

Using tarball UBUNTU 18.04 LAMP. I will try again on monday and than post again.
I have solved the problem. It was the installation of php 5.6 and the mysqli driver.
Thank you.
I installed php 7.2 and it worked.
