Giving the whole backsotry.
I upĺoaded all files from version 2.1.3 using git to a remote Ubuntu server and I got the following error
Vendor autoload is not found. Please run 'composer install' under application root directory
I googled a bit and found this http://www.technetexperts.com/web/magento-2-installation-guide/
After that, it started appearing the error
pelago/emogrifier v0.1.1 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system, which lead me to this page https://stackoverflow.com/questions/32943762/composer-install-issues. I installed all extensions following these steps and the
magento-check.php that I found somewhere.
After all that, I get error 500 on my home page and have no idea on how to proceed. Does anyone know what might be happening? Am I missing something?
