Hi,

PHP has a timeout limit for script execution. You can try increasing this value to allow more time for the template installation process

In php.ini file increase the value of max_execution_time setting, for example, to 300 (5 minutes). Restart your PHP and Nginx services after making the change.

Try again after making this change.

I raised the max_execution_time to 300 but I still get the error.

I've looked at the phpinfo and can see that the configh was successfully loaded.

Hi,

Also adjust the Nginx timeout settings. Look for the proxy_read_timeout directive in your Nginx configuration file (usually located at /etc/nginx/nginx.conf or within a virtual host configuration file). Increase its value to a higher value, such as 300 (5 minutes). Save the changes and restart Nginx.

clear the cache and try again.

I followed that tutorial: https://geekrewind.com/how-to-install-prestashop-on-ubuntu-20-04-18-04-with-nginx-and-lets-encrypt/
But since php7.4 is eol I used php8.2
(maybe this helps finding/resolving the problem)

Hi, Kindly follow below steps to check if the issue resolves,

  • Check CPU, memory, and disk usage during the installation process.
  • Monitor the Nginx access and error logs.
  • Clear cache and restart services

If this doesn't work still, then Consider creating a new clean installation of PrestaShop just in case if that installs the template files properly.

The cpu and cache doesn't seem to be the problem, when I look at the prestashop error log file I see this:

Hi,

The error message you provided indicates that the constant _PS_DO_NOT_LOAD_CONFIGURATION_ is being defined multiple times, which is causing a PHP warning during the template installation process in PrestaShop. This could be a source of the timeout issue you're experiencing.

The constant is defined in the file /var/www/prestashop/install/controllers/http/smarty_compile.php on line 26. Verify if the constant is defined there. Also, search for any other occurrences of the constant in your PrestaShop files to check if it's defined elsewhere.

If you find multiple occurrences of the constant _PS_DO_NOT_LOAD_CONFIGURATION_, remove all but one of them.

Clear the cache and install again. This should resolve the issue. Let me know if this helps.

This doesn't seems to be the problem. _PS_DO_NOT_LOAD_CONFIGURATION_ only occures in two files, the first is the mentioned smarty_compile.php and the other is inside the config folder a fallback option. Removing (commenting) these lines resultet in a 500 error to  be thrown with the cause that _PS_DO_NOT_LOAD_CONFIGURATION_ isn't defined.

 

I cleard everything, logs, configuration, prestashop webserver dir and remade everything. This now appeard in the logs:
