Hola, como actualizo su prestashop?

1.- Manualmente? 

2.- Modulo One Clik update.

3.- Composer?

 

Que version es exactamente 1.7.x??

 

Tiene algun backup?

[JENNY14]

Hola. Lo actualice con One Click Update.

Version prestashop: 1.7.6.5

No tenia backup =(

O te preocupes simplemente upgradea php a 7.2 y configuralo (instalar modulos, max_imput_vars, etc.) 

funciona comprobado, hice un upgrade (hice backup pero no lo necesite). solo debes cumplir los requerimientos de esa version Prestashop es más exigente con PHP.
