This appears to be due to the following line within your .htaccess:

[15:50:19 aem root@8483997 /home/aemadminuser/public_html]cPs# grep SetEnv /home/aemadminuser/public_html/.htaccess
SetEnv MAGE_IS_DEVELOPER_MODE "true"

This is due to mod_env not being installed on the server. You can install this Apache module via WHM by navigating to EasyApache 4 under the Apache Modules. If you would like I would be more than happy to assist with enabling this module however you will need to ensure that our IP addresses are able to successfully access WHM. I have included these IP addresses for you below:

Couldn't access - bug with apacheeasy4

via the command line:

Installing:

ea-apache24-mod_env | x86_64
2.4.25-9.9.2.cpanel | EA4 27k

Upon completion I no longer received any errors within the Apache error_log however there was still an HTTP 500 error being generated by the Magento script. This contained the following error:

[17-May-2017 23:37:59 UTC] PHP Fatal error:  Uncaught exception 'Zend\Stdlib\Exception\RuntimeException' with message 'No wrapper found supporting "UTF-8"' in /home/aemadminuser/public_html/vendor/zendframework/zend-stdlib/src/StringUtils.php:135

With a bit of research, I was able to determine that this was due missing the mbstring PHP extension. I went ahead and installed this and now both the URLs are loading without any errors:

Installing:

ea-php56-php-mbstring | x86_64                     
5.6.30-12.12.1.cpanel | EA4 523 k

my site now loads.

Answer 2

The following command allowed me to locate the correct packages:

# yum list | egrep 'iconv|intl|zip' | grep 56
ea-php56-php-iconv.x86_64                     5.6.30-12.12.1.cpanel    EA4      
ea-php56-php-intl.x86_64                      5.6.30-12.12.1.cpanel    EA4      
ea-php56-php-zip.x86_64                       5.6.30-12.12.1.cpanel    EA4      

You can use the following commands to install via command line:

# yum install ea-php56-php-iconv.x86_64
# yum install ea-php56-php-intl.x86_64
# yum install ea-php56-php-zip.x86_64
