I've upgraded a TYPO3 site from 6.2 to 7.6 LTS which now runs under a PHP 7.0 installation just fine. I also have a PHP application which I use to change a user's salted password (fe_user). The following code in my application worked fine under the 6.2 installation:
require Yii::app()->params['typo3Path'] . 'typo3/sysext/core/Classes/Core/Bootstrap.php';
define('TYPO3_MODE', 'FE');
\TYPO3\CMS\Core\Core\Bootstrap::getInstance()
baseSetup('typo3/')
loadConfigurationAndInitialize();
But now in the 7.6 installation, this code throws an exception:
Class 'TYPO3\CMS\Core\Core\ApplicationContext' not found
Any ideas? Is there an "official" way to change a TYPO3 user's password from an API or something?
