PrestaShop needs a few additions to PHP and MySQL in order to fully work. Make sure that your PHP configuration has the following extensions and settings configured:


  • CURL. The Client URL extension is used to download remote resources like modules and localization packages.
  • DOM. The DOM extension is needed to parse XML documents. PrestaShop uses it for various functionalities, like the Store Locator. It is also used by some modules, as well as the pear_xml_parse library.
  • Fileinfo. The File information extension is used to find out the file type of uploaded files.
  • GD. The GD extension is used to create thumbnails for the images that you upload.
  • Intl. The Internationalization extension is used to display localized data, such as amounts in different currencies.
  • Mbstring. The Multibyte string extension to perform string operations everywhere.
  • Zip. The Zip extension is used to expand compressed files such as modules and localization packages.


  • allow_url_fopen enabled. This directive enables PrestaShop to access remote files, which is an essential part of the payment process, among others things. It is therefore imperative to have it set to On.

Here is a section of the php.ini file (the configuration file for PHP):

extension = php_mysql.dll
extension = php_gd2.dll
allow_url_fopen = On
allow_url_include = Off
