@Pratham271 it's still causing an error.

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

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

[Aditya-PS-05]

@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.
