The app/not-found.tsx only works in the app directory. However, almost all pages are in the pages/ directory.

The router cannot find the not-found page from app router and instead is looking for the 404 page in pages directory

[Pratham271]

@mfts but locally when I added 404 page it was not working properly. Can you explain me again please the changes that you suggested

Please review my pr.

[mfts]

@Pratham271 it's still causing an error.

Can you also share a screenshot of what this improved error page looks like?

[Pratham271]

@mfts by mistake I removed a closing div just before the p tag let me make it right

@mfts
Please merge this if everything is good.

@Pratham271 the search is currently not working. Also the buttons don't make sense, especially since an external visitor will see it and they may not have a papermark account so home, documents and settings are useless to them.

I will award you for your effort but close this PR for now.
