Hi @angelfreedomv, did you find a solution for this error?

The application doesn't have permission to write to /var/www/mconf-web/current/log/lograge_production.log. Check the permissions in /var/www/mconf-web/current/log/, make sure it's writable by mconf. If the file lograge_production.log doesn't exist, you can also try to create it, giving write permission for mconf.
