Here are some examples of url mistakes that could've been made, or in general ways you could encounter this
-
Entered a url I dont have at all, like not even close (like leeolaaj.neocities.org/urmom) WHY DO U THINK I WOULD HAVE A URMOM.HTML
-
Typed too fast and therefore it is misspelt (like leeolaaj.neocities.org/announcemnts or /aanoucnemnts
-
Typed the wrong name for the page, but still had the idea of a page you wanted to go to (like leeolaaj.neocities.org/interests or /stuffIlike, the correct version would be /thingsIlike)
-
Link is either broken, or I am currently working on that page and dont have it linked yet (less common, but still happens sometimes)
-
Page is broken, and currently being fixed.
-
You clicked a link that goes to a page im planning to make the next day (I do that sometimes, on my end)
-
something somehow happened to the link? (if you are 100% sure this happened let me know pls)
