Installation error Class 'Twig_Template' not found

Support & Bugs

Hello,

I am trying to install Piwik on my server (with php 7.0). At a certain moment I get an error “500 Internal Server Error”.

I’ve set the /tmp folder a 777.

If I check the server error log, I see several errors:

  • FastCGI: incomplete headers (0 bytes) received from server “/var/run/php-fpm/php70/php-cgi”
  • FastCGI: server “/var/run/php-fpm/php70/php-cgi” stderr: PHP message: PHP Fatal error: Uncaught Error: Call to undefined function DI\string() in…/analytics/config/global.php
  • FastCGI: server “/var/run/php-fpm/php70/php-cgi” stderr: PHP message: PHP Fatal error: Uncaught Error: Call to undefined function DI\object() in …/analytics/config/environment/test.php:11
  • FastCGI: server “/var/run/php-fpm/php70/php-cgi” stderr: thrown in …/analytics/config/environment/test.php on line 11
  • FastCGI: server “/var/run/php-fpm/php70/php-cgi” stderr: PHP message: PHP Fatal error: Class ‘Twig_Template’ not found in …/analytics/tmp/templates_c/e1/e1910fc508f23b1cd864611e300dbb72048077070c211cc0ad667b9b8166af2b.php on line 4, referer: …/analytics/tmp/templates_c/e1/

Can you help me with the installation?

Thanks,
