Hi there,

Firstly, thank you so much for putting all your time and efforts into making this for us for free, I hope a lot of people donate to your by PayPal!

I have a bit of an issue

I uploaded 9.0.1, deleted old licence and uploaded new, renamed to License.php, ran setup, used a fake key

installed beautifully, went into admin, general settings, changed Company Name to my company name and save

and then I get

CONNECTION ERROR

WHMCS has not been able to verify your license for the last few days.

Before you can access your WHMCS Admin Area again, the license needs to be validated successfully. Please check & ensure that you don't have a firewall or DNS rule blocking outgoing connections to our website.

For help, see our documentation.

if I re-upload the licence file and re add a new fake key it works

if I go back into admin to change anything it does it again

I deleted and installed V8.13.1 and im getting exactly the same

thanks guys

any ideas please

Hi @wefixmacuk I haven’t received similar reports from other users experiencing this same issue. In order to properly analyze it, I’ll need to review it directly in your environment.

Could you please create a staging/testing environment and try to replicate the issue there? Once done, send me the access details to jesusdsuarezherrera@gmail.com using a secure link via privatebin.co.

I will need:

• FTP access
• WHMCS admin access

With this information, I’ll be able to review the issue and let you know exactly what’s happening.

Best regards,

@jesussuarz I have an inquiry relating to this project and I was wondering if we could communicate by email.

Sure!! send me a message.

Hi, I'm having the same license error problem. Every so often, after making modifications or changes and clicking save, I get the message:

CONNECTION ERROR

WHMCS has not been able to verify your license for the last few days.

After a few minutes of closing the page and logging back in, it disappears, but then it reappears.

i have installed your WHMCS all went ok but im seeing some outgoing connections from the script towards some AWS S3 IPs , is that normal!!

Yes, it's normal.

can you do same thing for chevereto?

I see a couple of people are having this issue as well so it's not isolated.

I get "404Not Found The resource requested could not be found on this server!"

Screenshot error link here: https://prnt.sc/EFIm7LOib1QS

O WHMCS 9.0 já foi lançado e ainda não está disponível no site, mas queria avisar.

Olá, obrigado, já está publicado.
Além disso, vários problemas relacionados à execução automática dos scripts foram corrigidos. Esses problemas eram causados ​​por uma configuração incorreta do cron, que impedia a execução dos scripts por um longo período. A configuração já foi revisada e o problema está totalmente resolvido.
Quanto ao arquivo license.php para a versão 9, estou trabalhando nele e espero publicá-lo nos próximos dias.

Ainda estou esperando aqui! Enquanto isso, não podemos usar o WHMCS 9, certo?

Acabei de publicar o arquivo de licença descriptografado e atualizado para o WHMCS 9.

Where can I download the license file?

Hello.
i currently have WHMCS 8.1.3 installed, owned license. It doesn't receive any further updates unless i buy a plan from whmcs.com

I want to upgrade to v 8.13 in order to benefit from PHP 8.3, is it possible to do a manual update using your License.php file?
Thanks.

hello

I just uploaded the license.php

and I tried to changed the key..

I feel when I access the admin , it is very slow and feel stuck , not smooth

how to solve this issue

thanks

I have also started getting these intermittent Connection errors: https://gist.github.com/jesussuarz/0b74fec85031a8e50d2f78187aaa46d3?permalink_comment_id=5975784#gistcomment-5975784

Has anyone found a fix? 8.13

Trying to update to v9.0.1. I am getting 404 error. I need help.

what's wrong admin login always fails

I have been a bit busy over the past few days, but I am now back.

Regarding the reported 404 errors, I have not been able to replicate any of them so far, so I do not have concrete evidence of these issues.

As for the error:

CONNECTION ERROR
WHMCS has not been able to verify your license for the last few days.

This error disappears after closing the page and logging in again, but it eventually reappears.

This behavior may be caused by WHMCS now replacing the license.php file when it detects an issue with the license.

As a possible solution, it is recommended to restrict write permissions on the license.php file by setting them to 444 (r-- r-- r--). This will allow WHMCS to read the file only, without making any further modifications.

Hello,

Problem with 404 I think is not script related, but server related, and here is why:
I was also constantly get 404 errors

Both on 8.13.1 and 9.0.2

First I was geting it when i click on login button in admin area, but that was my mistake, as I replaced license file only after instalation, when I did it before instalation, I did not get 404 error. Then I was geting it in admin panel when I save settings, and things like that.

And problem is cpanel OWASP mod security rules, as they were anyway last few months making me problem.
Since i added to etc/apache2/conf.d/modsec/modsec2.user.conf custom rules WHMCS works normaly.

An what are those custom rules? Can you share them, please?
Thanks.

I actually thought it could be something related to server security, a missing PHP dependency, or even an issue with the site’s rewrite rules configuration.

I’ve run several tests on my server and didn’t encounter any blocks or errors, so I’m confident this is not an issue with WHMCS or the license itself. It seems much more likely to be related to the server configuration, especially security rules like ModSecurity (OWASP), as you mentioned.

I would recommend reviewing or adjusting those rules on your server, as they are likely interfering with the system requests.

I tested it on my server with WHMCS and found that the issue is caused by the cPanel ModSecurity OWASP Mod Security Core Rule Set V3.0. After running some tests, and since I use Imunify360, I have cPanel’s ModSecurity disabled. However, the problem appears to be related to Rule 921130: HTTP Response Splitting Attack.

This is already documented here: https://whmcs.community/topic/312082-403-504-errors-modsecurity-being-triggered/

So this isn't the first time it's happened. It's been reported before.

An what are those custom rules? Can you share them, please? Thanks.

I can post them, but they contain security risk, I can do that for me, as my server is for internal customers only.
And for me I found different rules also affecting.
But I did not found reason why is admin panel so slow, but this is all WHMCS problems generaly.

Nice work keeping this module up to date! For anyone using WHMCS for subscriptions, integrating crypto payments can actually simplify things a lot, accepting cryptocurrency isn’t just convenient, it opens the door to global customers, reduces fees, and streamlines recurring billing. It’s something worth exploring if you want recurring payments to just work without extra overhead.

I see have update for 9.0.3, anyone try ?

最新版本 V 9.0.3出来了，请更新下载，等候佳音。

Ola pode me enviar o licence.php

Also, on version 9.0.2 the update does not work when trying to update to latest available it says already latest version but 9.0.3 is available latest and it does not fetch any update.. what could be the issue? is this normal expected or issue?

I see have update for 9.0.3, anyone try ?

update from 9.0.2 to 9.0.3 somehow does not work. it still says no update available and everything is updated already.

I've updated the versions on the site. The update system is probably not working properly, so manual updates will need to be performed until I fix it.
