When I follow this documentation to "Integrating IvoryCKEditorBundle to Create a WYSIWYG Editor" in my app, I get the following error:
[Symfony\Component\Debug\Exception\ClassNotFoundException] Attempted to load class "ZipArchive" from the global namespace. Did you forget a "use" statement?
This happens at the step 4. I really have no idea about what could triggers this error. Due to my OS configuration? PHP Version? Symfony config? Etc?
