Error 500 while install

Hello,

I’ve made wordpress websites before but for some reason this new one won’t work.

I’ve created a MySQL database, I’ve uploaded the wordpress directory, and now I’m trying to do the quick install process, but when I got to ~/wp-admin/install.php, it goes to ~/wp-admin/setup-config.php then nothing happens (Chromium says http error 500).

I then set all files and directories permissions to 755, but I get the same result.
So I edited the wp-config.php manually but I still get this error.

Am I missing something?
