Hi, I've recently used the free template with no problems, however all of a sudden the website's front end shows a 404 error message. (I'm not sure if the problem is on my host server side). The back end (administrator) is still accessible, and my home menu is pointing to a published article, however the error message is still there. I can access the front end by setting the website to offline mode (admin - global configuration) and logging in with my admin details. What is the cause of the problem?
