How to change 404 Not Found response to 410 Gone?

Sun, 13 Apr 2025 20:15:44 +0000

Hi everyone,

I'm trying to change the default 404 Not Found response in Question2Answer to 410 Gone, for some permanently removed pages.

I modified this core file:
qa-include/pages/qa-page-not-found.php

I replaced this line:
header('HTTP/1.0 404 Not Found');

with:
header($_SERVER['SERVER_PROTOCOL'] . ' 410 Gone');

However, when I test the page in the browser, I get a 200 OK response instead 410 Gone.

How can I properly make Q2A respond with a 410 Gone status code instead 404 Not Found?

Request for Assistance with Website Security and 404 Errors

My website was hacked, and I have deleted suspicious files, changed the password, and removed fake users. However, I am still unsure if the threat is completely gone. Additionally, the number of 404 errors has increased to over 5350 pages.

I need your assistance with:

1. Ensuring the complete security of the website.
2. Handling the large number of 404 errors.
3. Improving the site's re-indexing and performance in search engines.

I appreciate your guidance and advice on these matters.

Thank you for your help.

Tag doesn't find any question though one question has this tag

Sun, 01 Aug 2021 18:53:32 +0000

In a nutshell:

On my q2a instance I have a question (at this url) which has, among other words, the tags "incinérateur" and "décharge". However when I look for one of those tags [1] it says that no question is found (and the http code is 404).

Is this a bug or a behavior that I misunderstand?

My details:

I've also observed that when we look for other tags that are on this question, it works fine. For instance looking for the tag administration finds this question as expected
I've wondered if this behavior could be related to the tags with non ascii characters, but when I look for other tags with non ascii characters (example here) it correctly finds the associated questions
I'm using q2a version 1.8.5
Here the enabled plugin I have (not sure if it's relevant though):
- Akismet Spam Filter
- badges
- Category Description
- Event Logger
- Faq Page
- Logarithmic Tag Cloud Widget (nb: this is the only plugin related to tag that I'm using)
- Mouseover Layer
- Recent Events Widget
- WYSIWYG Editor
- XML Sitemap

[1]: ie: when we go to either the url for tag incinérateur or the url for the tag décharge

I deleted some fake users from QA but Google webmaster showing mw 404 error ? How to solved it ?

Fri, 28 Dec 2018 17:05:19 +0000

I removed all fake users but they were indexed in Google search result?

Now google shown me the message -

Googlebot for smartphones identified a significant increase in the number of URLs on that return a 404 (not found) error. If these pages exist on your desktop site, showing an error for mobile users can be a bad user experience. This misconfiguration can also prevent Google from showing the correct page in mobile search results. If these URLs don't exist, no action is necessary.

How to resolve it ?

404 Page Not Found throughout Q&A Forum

Wed, 13 Apr 2016 17:59:05 +0000

I have migrated the Q&A forum to a new server to launch a new website. I installed Question2Answer, and copied the DB over. It's there, and visible but when I try to login, or click any links, I get an 404 Page Not Found error. I think it has something to do with SEO friendly URLs, but I don't know where to go from here.

Any help would be appreciated.

Thanks!

404 message of Q2A core

Thu, 08 May 2014 05:48:39 +0000

In Q2A, page reading and several operation are limited by login state and user type (permission). Q2A may become user friendly by improving 404 message.

Example of qa-lang-main.php(141):

Before: "Page not found"
After: "Page not found. You may be able to access by login or register."

I thank nizar who gave hint to me.

404 problem with custom page

Sat, 31 Jul 2010 13:33:51 +0000

I am looking at creating a custom page (with PHP code) based on the related answer.

But there is a problem - because you're calling a page that Q2A doesn't think exists, it returns a 404 error (although the page displays fine).

Do we need to add something to the core to overcome this, or can we cancel the 404 header in the "main()" function?

EDIT: another issue: I'm following some code posted in other questions to obtain the current user. I have:
    $qa_login_user = qa_get_logged_in_user($qa_db);

But I just get "Fatal error: Call to undefined function qa_get_logged_in_user() ..."
I added an include for 'qa-app-user.php' at the top of the script but I still get the same error. Full code:

    require_once 'qa-include/qa-app-users.php';
    global $qa_db;
    $qa_login_user = qa_get_logged_in_user($qa_db);
