My site was working fine until just 3 minutes back, it started giving a fatal error all of a sudden. Fatal error: main() [function.require]: Failed opening required 'Zend/Controller/Request/Abstract.php' (include_path='.:/usr/php4/lib/php:/usr/local/php4/lib/php:/usr/lib/php:/usr/local/lib/php:/home/xxxxx/php') in /home/xxxxx/public_html/library/Zend/Controller/Request/Http.php on line 1065 Any idea what's wrong? Admin CP can't be accessed as well. Just thought I'd add that.
