When I go to /admin/config/development/configuration/full/export and want to export the full archive, the site loads for a while and then just goes completely blank and the URL bar shows /admin/config/development/configuration/full/export-download.

There is no error in the server log files and no entry in the Drupal reports.

In the sync directory sites\default\files\config_[...]\sync there is no file except for the .htaccess.

And when I try drush cex or drush cex sync this error occurs:

PHP Fatal error:  Declaration of Drush\Command\DrushInputAdapter::hasParameterOption($values) must be compatible with Symfony\Component\Console\Input\InputInterface::hasParameterOption($values, $onlyParams = false) in C:\Program Files (x86)\DevDesktop\tools\vendor\drush\drush\lib\Drush\Command\DrushInputAdapter.php on line 27

I've tried everything with the settings.local.php enabled and disabled. But the export just doesn't work. What can I do?

  • probably outdated drush or too new php version....just guessing. – user21641 Nov 14 '17 at 23:22

Firstly, What is the version of drush?

I advise that you use the console bundle(add it via composer: "drupal/console": "~1.0")

and then execute this command

drupal config:export  --directory="modules/custom/import_export_config/config/install/"
  • I installed the console with composer require drupal/console:~1.0 --prefer-dist --optimize-autoloader --sort-packages but then when I run drupal list I get Fatal error: Uncaught Error: Call to undefined method Drupal\Console\Core\Utils\DrupalFinder::getVendorDir() in vendor\drupal\console-core\src\Utils\DrupalFinder.php on line 41 – elterr1ble Nov 15 '17 at 13:02
