Hi,
I'm trying to install Prestashop v1.7 on my VPS based on Debian, but I always obtain a blank page after processing the unzip operations.
This is the procedure that I followed:
wget prestashop_1.7.0.6.zip
chown -R www-data:www-data *
Pointing the browser on the url it shows the processing bar and server unzips all files.
Then shows a blank page. At this point enabling debug
if (!defined('_PS_MODE_DEV_')) { define('_PS_MODE_DEV_', true); }
i can read these errors:
Warning: uasort() expects parameter 2 to be a valid callback, no array or string given in /var/www/shop.example.it/src/PrestaShopBundle/Install/LanguageList.php on line 87 Notice: Undefined index: in /var/www/shop.example.it/src/PrestaShopBundle/Install/LanguageList.php on line 123 Notice: Trying to get property of non-object in /var/www/shop.example.it/classes/Context.php on line 346 Catchable fatal error: Argument 1 passed to Symfony\Component\Finder\Finder::filter() must be an instance of Closure, unknown given, called in /var/www/shop.example.it/classes/Context.php on line 360 and defined in /var/www/shop.example.it/vendor/symfony/symfony/src/Symfony/Component/Finder/Finder.php on line 602
I do not have exprertise with PHP then I can not resolve by myself.
I will appreciate any help.
