Hi,

I’m a beginner with drupal/wamp and i don’t speak english. Sorry.

Wamp is ok. Drupal too. But if i install a module, (admin toolbar, webform,….) A fatal error message appear:

Fatal error: Cannot instantiate interface DrupalCoreCacheCacheBackendInterface in C:wamp64wwwdrupalcorelibDrupalComponentDependencyInjectionContainer.php on line 268
