The suggestions here about checking the core files and module settings are excellent. A simple thing that's often overlooked is the browser cache.
Sometimes the changes you make on the backend don't immediately reflect on the front end because the browser is showing a cached version of the page. It's always worth trying a hard refresh (Ctrl+F5) or clearing your browser's cache to see if that solves the issue. It's a quick fix that can sometimes save a lot of debugging time!
