Prestashop 9 - Nginx - Linux fresh Server

[bad_pussycat]

Hi I have installed Prestashop 9 on a new cloud server 

Frontend works but Backend I get HTTP 500
has the nginx config changed?

https://devdocs.prestashop-project.org/9/basics/installation/advanced/nginx/

Ubuntu 24.04   PHP8.3

thanks
Michael

additional information: today I activated debug mode and now also the admin works. But I don't see any errors so far.

Any Idea?

Welcome to new Prestashop world 😞 

[bad_pussycat]

sorry I looked for /var/log/nginx/* but in the internal log system in the admin UI I have errors

Cannot register tab "PsshippingCarrierController" because it already exists

like I said its a new installation on a fresh server one thing happened thing the installation (I thought my cloud server would be fast enough) I ran into a fast_cgi_timeout after setting the timeout higher in the nginx config I just reload the page (without deleting the db tables - I dunno if the install script took care of this correctly but I think I read it so I just reload and start the install again)

maybe this is the reason

anyway will install from scratch now again

Hey Michael, sounds like Prestashop is playing hide and seek with your backend! That HTTP 500 might be due to missing permissions or a misstep in the nginx config—double-check the fastcgi params. Also, make sure all PHP modules are good with 8.3. And hey, if your current server provider is making life tough, you might wanna peek at HostNoc—they know how to keep things running without drama!

New versions of prestashop are only for programmer-testers.

You have to wait a year or so until millions of bugs are fixed and only then can you try to run a store on it.

[bad_pussycat]

Ah sorry, I forgot to give feedback. It was all my fault! Like I said I ran into this fast_cgi_timeout and failed to drop the database while reinstalling. I installed again this time with a clean DB and it worked!

@ yabber This Version is officially released and not a development version anymore. And I like it!

PrestaShop does function well in NGNIX....this from a lot of experience, of course if you think it's ok, monitor for visitor 504's loooool

happy ps'ing...

The huge number of bugs reported on github contradicts such reasoning.

Just like the false information that prestashop 9 is compatible with PHP 8.4 https://github.com/PrestaShop/PrestaShop/issues/38985

Hi,

my experience is similar.

Frontend ok Backend no way

Fresh installation presta 9, fresh db fresh folder on webhost provider where I host also old presta versions that work fine.

front end works fine

backend no way to have access. 

Install folder deleted as usual

Admin folder automatically renamed by presta installer and or me same results, php8 php 81 82 and 84 same results. No way to access debugmode.
No idea what is going on.

Cheers

Boris

Are you guys serving with nginx? If so, please don't forget to write your admindir to the server config

 

    # [EDIT] Replace 'admin-dev' in this block with the name of your admin directory.
    location /admin-dev/ {
        try_files $uri $uri/ /admin-dev/index.php$is_args$args;
    }

@bad_pussycat

I ll try also this can you please share which file I have to edit in prestashop and where it is located? Take into account that I installed presta on a web hosting provider so there are configurations that I have not access.

Thank you

Hi Aeriko,

This is no Prestashop file!

If you installed on a web hosting provider and you don't have access to the server directly, I guess there is not much you ca do but to ask the staff of that said host. but chances are you host works with apache anyway and then you don't need to change anything (I guess Prestashop itself change the .htaccess file so you don't have to)

So your frontend works? And backend not?
What Error do you get?

I quickly tried an upgrade on a local docker container (was 8.2.0 I think) and get an ssl loop in back office login with nginx proxy manager so gave up until I have time to look at it properly. Maybe ssl handling has been "improved" or "updated". You can turn ssl off (in database) and back office works for me though.

SSL misconfiguration can give a 500 server error.
