无法在生产中运行Akeneo

I've decided to give Akeneo a try as it is exactly the product I need. I am unable to run the Production version of it, though. White screen of nothing shows up, with status code of 500. I've installed it according to the Installation tutorial on the Akeneo site, but all I am able to do, is access the app_dev.php (Development version of Akeneo). Why?

I have the right permissions set. app/logs show nothing related to production version.

I run Ubuntu 16.04 with PHP 7, MySQL 5.7.

Thank you for any suggestions!

A simple suggestion to start. Did you try to clear the symfony cache ?

app/console cache:clear --env=prod

or even:

rm -rf app/cache/* 

If you don't see any logs in app/logs, you may have a fatal error. You should check /var/log/apache2/akeneo-pim_error.log for any system or PHP error.
