Missing app/cache
Seme framework has cache directory for store the cache under app/cache/ directory.
But, this directory for now is not auto generated so you have to created manually the cache directory.
Example error message
Notice: Missing app/cache in /Application/xampp/htdocs/seme-frmamework
Notice: Missing app/cache in D:\xampp\htdocs\seme-framework
Notice: Missing app/cache in /opt/lampp/htdocs/seme-frameworkSolution
Create manually the directory app/cache.
