Ojs 3 installation problem - http error 500

I tried to install newest version OJS 3.1.2 twice, on two various servers… and when I click “install”, page with HTTP ERROR 500 appears.

What’s up? What can cause this problem and how to resolve it?

Earlier I had proper installation of earlier version of OJS on a one of these servers.

Error logs are: “Invalid command ‘\xef\xbb\xbf’, perhaps misspelled or defined by a module not included in the server configuration”

Hi @AiA,

See e.g.: mod rewrite - 500 Internal Server Error when using .htaccess with RewriteEngine - Stack Overflow

The problem is that I had no .htaccess file in the OJS folder.
So the first part rather isn’t the solution.

So, as I understand, I should check mod_rewrite module in apache?

Hi @AiA,

Somewhere on your server there’s an Apache configuration that Apache can’t parse. I’m afraid I can’t tell you where.
