Improve look&feel of the Kiwix Server 404 page

[kelson42]

The Kiwix Server 404 page is displayed when an HTML page is requested but does not exists in the ZIM file. A 404 error is an HTTP status codethat means the page you were trying to reach on a website couldn't be found on their server.

Today it looks like this:

This page should obviously localisable.

Here is the link: https://dev.library.kiwix.org/viewer#opentextbooks_en_all_2024-09/openstax.org/subject_does_not_exist

This scenario should happen rarely as ZIM are conceived to remove - as much as possible - the kind of dead links leading to such a page. But this error will always happen time to time.

Today the page is informative but really not fancy. We would like to improve it with a nice design and a Kiwix specific visual:

• Like the the dead Kiwix visual
• We have also a dedicated customised 404 logo

On my opinion we might not put more in emphasis the "404" which is a pure HTTP error and in some cases the readers are not HTTP related, so this might be abusive.

Here a few very nice 404 pages

Hi @kelson42 . Can you just clarify your last phrase, you would like a 404 reference, or not? Thanks.

I suspect that it would be better to not make an explicit reference to the code "404", neither in the text, nor in the visual.

Hi. Here are some first ideas.

@siemsie Thank you! We will gather feedbacks so we can make an educated chose/response
@juuz0 @veloman-yunkan @rgaudin @Popolechien @sgourdas @benoit74 @ShaopengLin Your feedback is welcome about what is good and what could/should be improved.

V1 looks nice but why not go with the 404 we already have on our website?

There is a bit of text on top

Sorry – we can't find what you are looking for!
We are sorry, the page you requested could not be found.
Please go back to the [homepage](https://kiwix.org/en)

I agree that we must not mention 404, this means nothing to most users.

My preference is for version 2.

I would prefer to revisit a bit wording:

• The request URL => The requested path or The requested ZIM item (with a preference for "path" for simplificity)
• not found on this server => not found in this ZIM

Regarding the "Make a full text search for ..." paragraph, I feel like it provides way more frustration than value. It is very technical ("full-text search" is a complex term) and very very rarely works from my experience. I would at least replace it with a constant text with something like You might want to search for this content instead of accessing it via the link you just clicked, maybe this is just a broken link issue and this content is present at another path in the ZIM. And not automatically suggest search terms which are mostly always bad in my experience.

• I find the v1 too different from the usual visual of kiwix-serve
• I find both v2 and v3 to not convey the proper meaning.
• I find the 404 to be too tied to understanding what 404 stands for which is probably not the case for a huge share of our user base.

I agree with @benoit74 on the wording

These are images we already have (I made v5 with the ?). Could there be something there that works better?

Either way, need to have consensus on the overall message to find a suitable image. Are we lost? Is it broken?

While I feel that the 404 is not essential for the every day user to see, I observe that most webpages still choose to display it in some minor way. It seems like everyone understands the general meaning of it, after getting used to seeing it everywhere.

As far for the samples, I am in favor of being consistent with the main website as @Popolechien mentioned, but we should keep the focus on the important details of what happened. In that sense the 404 could be put beside a bigger image of v3, v4/v5 or v6, so they can be used together.

I also think that it is good to provide some getaway resources like links to the home page and more direct and relevant hints like @benoit74 mentioned.
