Hi @nickPostma,

It seems like a permission problems.

Maybe the owner of files isn't the same user than webserver. Is it possible?

[nickPostma]

Reconfigured owner of files to be the nobody user, gave them full permissions. now I see this error:

PHP Fatal error: Uncaught exception 'Zend_Cache_Exception' with message 'cache_dir "/var/www/html/magento/var/page_cache" is not writable' in /var/www/html/magento/vendor/magento/zendframework1/library/Zend/Cache.php:209\nStack trace:\n#0 /var/www/html/magento/vendor/magento/zendframework1/library/Zend/Cache/Backend/File.php(180): Zend_Cache::throwException('cache_dir "/var...')\n#1 /var/www/html/magento/vendor/colinmollenhour/cache-backend-file/File.php(87): Zend_Cache_Backend_File->setCacheDir('/var/www/html/m...')\n#2 /var/www/html/magento/vendor/magento/zendframework1/library/Zend/Cache.php(153): Cm_Cache_Backend_File->__construct(Array)\n#3 /var/www/html/magento/vendor/magento/zendframework1/library/Zend/Cache.php(94): Zend_Cache::_makeBackend('Cm_Cache_Backen...', Array, true, true)\n#4 /var/www/html/magento/vendor/magento/framework/App/Cache/Frontend/Factory.php(156): Zend_Cache::factory('Magento\\\\Framewo...', 'Cm_Cache_Backen...', Array, Array, true, true, true)\n#5 /var/www/html/magento/vendor/magento/framework/App/Cache/Fr in /var/www/html/magento/vendor/magento/zendframework1/library/Zend/Cache.php on line 209

Could you please provide the ideal user setup, with permission configuration?

@nickPostma,

Here you'll find the information you're looking for: http://devdocs.magento.com/guides/v2.1/install-gde/prereq/file-sys-perms-over.html

[nickPostma]

Thank you! I added a new user and added them to the apache users group and gave ownership of the docs to that group and I got past the error

[Damian Culotta]

Great!

Can you mark the answer that help you to get the solution? (in order to help future users with the same problem).

[nickPostma]

Retested and it's still not working, 

permissions are set 777 for all files under magento directory,

user group apache owns the files and magento_user belongs to that group...

What am I missing?

[Damian Culotta]

Can you check if users and group has the same level of perrmissions?

Can you show the permissions and owners of a few files with both users?
