Magento 2: 500 Internal Server Error
I followed the Magento dev docs per below:
If you add a new .html template, and then edit it, the changes will not apply until you do the following: delete all files in the pub/static/frontend and var/view_preprocessing directories, then reload the pages. You can delete the files manually or run the grunt clean: command in CLI. For details about using Grunt in Magento see Installing and configuring Grunt.
However now in developer mode set via htaccess I get Internal Server Error 500 across site and admin urls. Is that a caching issue if its looking for the cleared files to render?
in developer mode the files are automatically generated when requested and not found. So this should not be a Problem.
When facing a 500 error the first thing you should do is search for your webserver error log.
When running on apache it can mostly be found in one of these 2 locations:
/var/log/httpd/ -> centos, archlinux ...
/var/log/apache2/ -> debian, ubuntu ...
