I get the following error in my shop, after it had worked normally:

Fatal error: Class 'Varien_Cache_Core' not found in /public_html/lib/Zend/Cache.php on line 195

It breaks the entire website, and I have no idea why, as it happened without any lead.

All folders have been given 777 permission, to make sure that wasn't the problem.

Any idea where I should look for this?

  • does /public_html/lib/Zend/Cache/Core.php exist?

Check your permissions for files as well as folders (http://www.magentocommerce.com/wiki/1_-_installation_and_configuration/magento_filesystem_permissions). Also, clear your /var/cache/ and /var/sessions/ folders. If you've enable compilation, disable it, and cycle your cache from within the admin system if you can access it.

The problem was a full server, making several files half empty or non-existant.
