Hi @omnison

Try to run following command in the magento root

php bin/magento setup:static-content:deploy

I had also a error 500 when trying to login to /admin

I got redirected to /admin/admin/index/index

Not sure how I got my solution to finally view the /admin but this steps I took:

1. I made sure the path works in php.ini:
   session.save_path = "/path/to/magento/websites/project/magento2/var/tmp"
2. I switched from PHP 7 to 5.6. and back to 7
3. I deleted the script in app/code/magento/backend/view/adminhtml/templates/search.phtml (line 28 to 60) because line 43 created temporarely a error while I logged in to /admin

Hope this helps someone.

check php version Magento ?2.0 requires PHP >7.0 in .htaccess, you can point to the needed php version using the correct handler:

<code>#enable php 7
AddHandler application/x-httpd-php70 .php

</code>

you could also enable development mode in .htaccess to get detailed PhP error messages:

<code>

SetEnv MAGE_MODE developer

</code>

Please check .htaccess first.possibility of module not enabled. Because i faced this issue because of mod_version module so I enabled it from apache and now it's working. I had installed magento version 2 via composer.

You can check also with replacing your .htaccess file Or renamed it to confirm issue of .htaccess file.

-and if css not properly working then please deploy static content 
php  bin/magento setup:static-content:deploy

You need switch magento to developer mode for find exact error text. Issue can be related with permissions on files, static content, errors in templates. << Snipped >>
