Worked for me - maybe you should redownload the demo zip file.

Have you tried a different PHP version?

Hello z0r0z,

Thanks for your answer. Strange but I have not the same code in the custom.sql file. But I got the error with it.
And when I now try to install the demo environment with PHP 8.4.17 I got this error : Duplicate entry '886-8' for key 'PRIMARY'

In my custom.sql file the code is already like the solution tells : INSERT INTO `#__schemas` VALUES (21,'5.0.0-2023-09-11'),(1254,'4.0.0-2021-08-13');

I don't understand why I got the other error when I tried it in August 2025.

The solution is described here: https://www.joomla51.com/forum/nina-demo-not-instaling-properly

PHP version is 8.3

Which PHP version is set?

We haven't heard from Ciaran for several months now, and he's not answering any questions via email. He's vanished without a trace…

Hi Kees,

Thanks, If I find a solution I will let you know - otherwise I will also use a different template.

Regards
Paul

Hello Paul,

No I did not resolve this, because I don't know how. I have used another template.
Unfortunately I got no response from Ciaran like I was used to before. You usually received a response within a few days, almost always with the correct solution.

So I bought Nina and can't use it like I want.

Best regards
Kees

Hi, did you manage to resolve this? I have the same issue.
