PrestaShop 1.7.4 / 1.7.3 - Install error - xmlfileloader.php - symfony

[vbb]

Hello,

if i install PrestaShop 1.7.4 or 1.7.3 i get a error at 0% (Create file parameters). 

Requirements are all installed. On 1.7.4 i get a ICU warning, because i use ICU 60.2. I tryed 1.7.3 which works with ICU 60.2, no warnings but the same error.

 

Rights:

User/Group: www-data:

chmod: 755 and 777 tryed - same error 

 

Apache Error Log:

Hi,

Not sure but it seems php-xml extension is not installed. Kindly ensure that php-xml extension is installed.

Any help with this one? I disabled Litespeed Cache module and I am getting the same issue.

 

I think it has something regarding group permission or something like that, because anything that I modify, update modules, etc, the same Error 500 is displayed with that error code:

Quick solution:

- Download the used Prestashop version and unzip folder symphony and replace it on your webserver

- If you are using another version of PHP, other than the recommended one, then you might have issues, so switch to recommended from within your Cpanel account.

This should solve your problem, it solved mine which was the same as yours.

Hola.

He sustituido la carpeta symphony de los archivos de instalación de Prestashop version 1.7.6.2 y continuo con el mismo mensaje.

He cambiado a PHP 7.3 y al realizar el cambio y probar me aroja error 500.

Alguien sabe como solucionarlo?

Gracias!!

Hola,

Está utilizando una versión PHP incompatible con su versión actual de Prestashop.

Lea más sobre la lista de compatibilidad: https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

Si obtiene los mismos errores que yo, la solución es simple:

1. Activar PHP 7.1 de CPanel. También puedes probar con PHP 7.2, tal vez funcione con eso.
2. Reemplace los archivos de la carpeta Symphony con los mismos archivos que en su versión Prestashop 1.7.6.2 (descárguelo de Prestashop): https://assets.prestashop2.com/en/system/files/ps_releases/prestashop_1.7.6.2_0.zip
