"Fatal error" on installation


#1

Hi, I upload the latest version to mysite.com/analytics (unziped), and when access to the url to install Matomo I got this error instead the " Welcome Screen":

Fatal error : Class ‘DI\Definition\Source\Autowiring’ not found in /[redacted]/public_html/analytics/vendor/php-di/php-di/src/DI/ContainerBuilder.php on line 118
Matomo encountered an error: Class ‘DI\Definition\Source\Autowiring’ not found (which lead to: The root container has not been created yet.)
Fatal error : Uncaught exception ‘Piwik\Container\ContainerDoesNotExistException’ with message ‘The root container has not been created yet.’ in /[redacted]/public_html/analytics/core/Container/StaticContainer.php:40 Stack trace: #0 /[redacted]/public_html/analytics/core/Container/StaticContainer.php(80): Piwik\Container\StaticContainer::getContainer() #1 /[redacted]/public_html/analytics/core/Log.php(94): Piwik\Container\StaticContainer::get(‘Piwik\Log’) #2 /[redacted]/public_html/analytics/core/Log.php(225): Piwik\Log::getInstance() #3 /[redacted]/public_html/analytics/core/Log.php(172): Piwik\Log::logMessage(100, Object(Piwik\Container\ContainerDoesNotExistException), Array) #4 /[redacted]/public_html/analytics/core/FrontController.php(214): Piwik\Log::debug(Object(Piwik\Container\ContainerDoesNotExistException)) #5 [internal function]: Piwik\FrontController->__destruct() #6 {main} thrown in /[redacted]/public_html/analytics/core/Container/StaticContainer.php on line 40

I have a Hostgator shared hosting with PHP 5.5.

Hope you can help me to get this installed.

I’m not an expert on this topics, I’m following this guide Installing Matomo - Analytics Platform - Matomo

Thanks.
