I just finished with this whole website and all is working fine, I want to install french pack via ssh, I had problem with memory so I used root access to install and the installation was successful,
when I turned back to the website I couldn't access and I get this
Error 500 - Internal Server Error An error was encountered while processing your request. Typically this is a temporary condition. Please contact the web site owner for further assistance.
when I delete .htaccess
I can access the front page only with no css, If I click on a link I got 404 Error
the module doesn't appear when I check modules status using
php bin/magento module:status
so I can't disable or delete it, even if I rename the vendor/imaginaerum folder nothing change
I also ran
find . -type d -exec chmod 500 {} \;
find . -type f -exec chmod 664 {} \;
chmod 777 -R downloader var media
to fix if any file permission but no result also
the French package I've installed http://imaginaerum.github.io/magento2-language-fr-fr/
