0 down vote favorite MY Joomla 3.1 site is down with showing ERROR 0 on front end. Last day it works fine but today when I am trying to access my site it throws error. The interesting thing is that I can still access backed/ administrator part of the site. I am not able to show the site as it is an internal site but I am attaching the screenshot of the error page. Please help.
Go to administration -> system -> global configuration -> server and set Error reporting to development. You can also turn on Debug system under global configuration -> system. Than you will have more informations about error.
