v1.0.0-amstel white screen

[adian666]

Hello,
After adding a theme v1.0.0-amstel in Prestashop 1.6.1.16 and clicking "Preferences-Themes-Use this theme" a white screen shows. An error_log on ftp occurs: [11-Aug-2017 15:02:15 Europe/Berlin] PHP Parse error:  syntax error, unexpected '[' in /public_html/polishmultipool.pl/vendor/react/promise/src/functions.php on line 15.

 

The cache is off and compression is on. Theme version is compatible with Prestashop version. The theme is bought on official website addons.prestashop.com.

What can be the reason of not working?

What is your PHP version ?

 

You can find info in Advanced Parameters >Configuration Information.

PHP version: 5.3.29

 

Yes error appears because because of that. So you could change /vendor/react/promise/src/functions.php on line 15 

code from for example 

$a = ['one' => 1, 'two' => 2, 'three' => 3, 'four' => 4];

but that is feature from 5.4 so you can change that to 

$a = array('one' => 1, 'two' => 2, 'three' => 3, 'four' => 4);.

Also you can ask your hosting to upgrade PHP to 5.6.31 for example, but you would need to check whole store to see if all works correctly in that version.

Thank you for the help

It was possible to work around without changing the files.

I forced php version change via .php56 file
