A few months ago I got the OJS system to successfully install on my stack (PHP 5.6, MariaDB, Nginx, Ubuntu 14.04). But it suddenly stopped working, and now I can’t re-install it, not even a fresh install.
I get to the install page: example.com/index.php?journal=index&page=install. But when clicking the “Install Open Journal Systems” button, and get redirected to example.com/index.php?journal=index&page=install&op=install I get a 500 error.
I’ve done the installation steps (giving 777 permission to uploads, cache, public and config.inc.php) many times, and even changed my virtual machine. No luck, any help?
