I have recently moved to DigitalOcean and trying to test it out. I have a Mediawiki website on the localhost that i want to move the server. But for that I need to install Mediawiki on the server first. When I am trying to install it by using the tutorial here: https://www.cloudways.com/blog/install-mediawiki/ and this: https://www.rosehosting.com/blog/how-to-install-mediawiki-on-debian-wheezy/

However, after installation is done i try to access the page but getting 500 error. Does anyone know what could be the issue?
