i bet you changed something in core_navigation.tpl or so.. just take the original one or install xampp and try to replace changed files on a second installation with the original files
You generally have two options when it comes to the navigation…
Using the default provided by the system and modify it by moving it to your skins directory and editing it as you see fit.
Creating a brand new navigation system from scratch or borrowed code.
Either two end with the same outcome. But in this particular situation it would be most helpful to know which one exactly you are doing in order for us to make a more accurate assessment of what exactly went wrong. Also something to take in note is how the skin is structured. The header.tpl is always at the top, the footer.tpl is always at the bottom and the content generated by the system is always sandwiched in between. So the moral of the story is to double check that you are adding your navigation to the header.tpl and not your frontpage_main.tpl or etc.
its all set up and i changed the directories in core_navigation.tpl, it worked, but only on the frontpage for some reason, then i tried some editing, and unfortuanely forgot to back up and now ive lost the menubar and my banner.
ok i started from scratch lol, i have my default nav bar, but i want to add a CSS nav bar but im scared ill loose everything again, can someone help me do this ? as i havent got a clue if what im doing is right or wrong, still a beginner at website design, but keen to learn.
