So, I own a website for my Let's Play group. The leader of the group asked me to add a wiki to the site, so I took on the challenge. At first, I went to the host's website and logged in as admin of the site. I browsed the things I can do, and one of the options was "Automatic Installer" or something, so I clicked on that. I scrolled down a ways to the "Wikis" section, where I found MediaWiki. I clicked, set the admin username, password, and the directory to install to, and it went on its way. A few minutes later, it said it finished, so I clicked on it. An error message came up, saying "Incorrect installation" followed by an error code I didn't bother to read. So, I went to this MediaWiki page, and I did it as it said. Different error, though. It failed to find a database, so I went to this link on the MediaWiki page. I currently have MySQL installed, but I have no idea what to do in it. This section tells me to do some commands, but they end up not working. Any ideas?
