#2650 – Problem with blog format

Hi

This 404 is generated by your server, not by Joomla (or sh404SEF). This means you have not enabled and configured URL rewriting on your server.

URL rewriting on your server is needed if you want to have URLs such as https://xxxx.com/webinar/bigbluebutton/

Without URL rewriting, URLs can only be similar to https://xxxx.com/index.php/webinar/bigbluebutton/

This is outlined in the Getting started guide: the first thing to do is to configure your server and Joomla:

sh404SEF extends Joomla! default SEF URLs system, so the first step is simply to enable Joomla! SEF URLs, and have them working properly before you attempt to switch sh404SEF on.



Enabling SEF URLs involves:



setting up your web server

activating SEF URLs in Joomla! configuration

selecting whether your server uses URL rewriting

This process is very well documented on this Joomla! documentation site page.

The link to the Joomla documentation page to help you configure your web server is: https://docs.joomla.org/Enabling_Search_Engine_Friendly_(SEF)_URLs

If you cannot configure your server properly, then you should set Jooma "Use URL rewriting" to "No". URLs will have "index.php" inserted in the middle, but at least they should work normally.

I would also suggest that during this phase, you disable sh404SEF (Enable URL optimization set to "No"). When you have Joomla SEF working, it will also work with sh404SEF, as there is no additional requirements on sh404SEF side.

Hope it helps

Hi

The rest of the configuration and server joomla is correct, the problem is sh404sef

Once again, this is NOT related to Joomla or sh404SEF.

At this moment, this page seems to work fine, so I cannot do a screenshot, but when I visited the first time, the error was a NGINX 404 error page. That means the request for that page does not reach Joomla.

As you are still running Nginx, and the page works fine, I think you probably found the source of the problem in the mean time.

Hi

Hello again , the page is working well because right now is running Apache. Until we can fix this.

The page is running on Nginx and is working fine.

[xxxx]

I am confused, what's going in here?

Please get back to me when the page is NOT working and I can see it. Otherwise, we can't understand what's happening.

HI

So you have a different web server for front end and backend? That's pretty unusual.

Anyway, I can see it again, and I can confirm, with a screenshot this is a nginx, web server issue:

[xxxx]

As you can see on the screenshot, this error is NOT generated by Joomla. The request is not even coming to Joomla (or sh404SEF). It's thrown directly by your webserver.

If you say that it works fine with only Joomla SEF, then I'm pretty sure it's an issue with the trailing slash.

Can you disable sh404SEF, and note what is the exact URL for this same page?

Rgds

Hi

Exactly what I guessed above: your nginx server is not configured properly: it doesn't recognize URLs with a trailing slash.

Just try try with that same URL with a trailing slash:

[xxxx]

You get the same 404 error from nginx:
[xxxx]

Hi

Sorry, this is not a correct fix. What you are doing here is redirecting URLs with slash to the same URL without a slash. That's not good, and I don't event think it will work with sh404SEF, because with sh404SEF, the URL without a trailing slash does not exist and is a 404. Actually, sh404SEF will normally try to redirect /my-category to /my-category/, and then your nginx config will also try to redirect the other way around, resulting in an infinite loop.

The correct fix is simply to have nginx serve all URLs, with or without trailing slash. That's the most normal configuration, I'm not sure why this is not happening on your server, but that's where you have to look I think.

Maybe this can help you, here is a standard nginx config for handling Joomla URL rewriting

location / {
    
        index  index.html index.php;
        
        # serve static files that exist without running other rewrite tests
        if (-f $request_filename) {
            expires  30d;
            break;
        }

        # send all non-existing file or directory requests to index.php
        try_files $uri $uri/ /index.php?$args;
    }
