Hello,

We are experiencing an issue with the Request Quote / Email Cart functionality when running J2Store / 2commerce on PHP 8.4.

Environment:

• Joomla: 6.x

• J2Store / 2commerce: latest version

• PHP: 8.4

• Mail configuration: Joomla core mail (tested and working in other contexts)

Issue description:

• The core J2Store component itself works correctly on PHP 8.4.

• When using Request Quote / Email Cart, the request process starts normally (loading spinner appears).

• However, the email is not sent to the administrator.

• The process eventually stops without any visible frontend error or message.

Expected behavior:

• The Request Quote / Email Cart form should send an email to the administrator as usual.

Actual behavior:

• No email is sent.

• No visible error is shown on the frontend.

Notes:

• This issue does not occur on earlier PHP versions (e.g. PHP 8.3).

• Could you please advise whether this is a known issue with PHP 8.4, and if there is a fix or recommended workaround available?

Thank you in advance for your support.

Ok, i update it.

Hello,

Thank you for your response and for the link to the Joomla 6.0.2 known issue.

The website was built from scratch. The installation and update sequence was as follows:

1. A clean Joomla 5 installation was performed

2. J2Store / J2Commerce and Request Quote / Email Cart were installed

3. The entire system was upgraded to Joomla 6

4. After that, the PHP version was upgraded

During testing, the following results were observed:

• With PHP 8.3 → Request Quote / Email Cart works correctly, emails are sent

• With PHP 8.4 → Request Quote / Email Cart does not send emails

• The same behavior is reproduced on:

  • Joomla 6.0.0

  • Joomla 6.0.1

  • Joomla 6.0.2

During testing, no changes were made to the J2Commerce or Request Quote / Email Cart configuration – the only parameter that was changed was the PHP version.

Based on these tests, I believe that the situation is unlikely to change with Joomla 6.0.3, as the issue is fully reproducible across multiple Joomla 6 versions and only occurs when PHP 8.4 is used.

It is likely that the issue is related to the F0F (Framework on Framework) layer or its compatibility with PHP 8.4.

I hope that this will be resolved with J2Commerce 4.1.0.
Could you please advise when this version is planned to be released?

I would also like to clarify:

• whether Request Quote / Email Cart will require a separate update together with J2Commerce 4.1.0, or

• whether compatibility will be ensured automatically as part of the J2Commerce update.

Thank you in advance for the information.

Best regards,
Sergiejus

Thank you for the clarification.

Yes, I would be happy to test the new v4.1 beta version. I do have a testing environment available, so you can safely share the package.

Please feel free to send it via WeTransfer.
Looking forward to testing it.

Thank you!

Best regards,
Sergiejus

Thank you! I really appreciate it.

Hello Olivier,

This version works identically to the previous one.
I haven’t encountered any errors, however it does not work on PHP 8.4.

I will wait for the next updates of Joomla itself and this component.

Best regards,
Sergiejus

Hello Olivier,

I have re-enabled your access to the test website.

I would appreciate it if you could try again.

Thank you,
Sergiejus

Hello,

thank you for checking and for pointing me in the right direction.

After your comment I performed additional tests and it turned out the issue is not related to J2Commerce nor Joomla. I discovered that in my hosting environment PHP 8.4 fails TLS/SSL certificate verification, therefore the server cannot send emails via SMTP at all (HTTPS requests from PHP also fail).

I have contacted my hosting provider and asked them to fix this on the server side. Once the problem is resolved, I will re-test with PHP 8.4 and come back with the results.

Thank you again for your help.

Sergiejus

The issue is resolved.

The hosting provider had an incorrect PHP 8.4 OpenSSL/TLS configuration.

After they fixed the server environment, Joomla test email and J2Store Email Cart both work correctly on PHP 8.4 and Joomla 6.0.3.

Thank you for your help.
