    Presta 1.7x does not works with PHP 7.+???


    Now installing PHP 5.6 then, but on any other update... Presta 1.7x and further is going to give conflicts?

    Just predicting…

    At the moment, PrestaShop 1.7 is supporting 5.6, as for the future versions, I suggest checking PrestaShop official site and forum as they might have posted some announcements about PHP 7.+.

    Hello @hooman.zaman,

    Thank you for the suggestion.

    Generally, PrestaShop 1.7x supports PHP 5.6.

    The error message is incorrect and will be changed in future updates.

    The recommended workaround for using PrestaShop and PHP 7.2 is presented in the resolution section.
