404 Joomla Error Page Not Found

Hi, I deleted the main menu module and menu and now I'm getting a 404 Joomla error on the public page. I haven't done much with this installation, what did I delete that I shouldn't have?

How about deleted the main menu? If you dont wanna show it disable it. It has a property called Default, Without a defalt users coming to the site with no home.html or index.html or index.php

Disable it so its not shown but still used

Ok. So what can I do now?

In your module manager where you deleted it click New Module

Menu -> Next


Fill in Title, Select, Enable No (we are doing this already because you deleted it) Select mainmenu in Menu Name field and I hope I didnt have to animate this to make you know your to click Save next
