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?
