I am working on a new website development with Joomla 3.1. The menu links were working fine before. However, suddenly one of the menu link now leads to the 404 error page.
It happened once before and I fixed it by changing the menu alias. I wonder why and how the old alias which was working fine before is now creating a problem.
The menu item is not locked. It is in published state. Similarly, the article assigned to it is also not locked and is in published state.
Any help/insight please?
