Everything was working great and then boom:

Warning: require_once(/home/lalaami/amimiboutique.com/concrete/config/../libraries/cache/abstract.php) [function.require-once]: failed to open stream: No such file or directory in /home/lalaami/amimiboutique.com/concrete/libraries/loader.php on line 35

Fatal error: require_once() [function.require]: Failed opening required '/home/lalaami/amimiboutique.com/concrete/config/../libraries/cache/abstract.php' (include_path='.::/home/lalaami/amimiboutique.com/libraries/3rdparty:/home/lalaami/amimiboutique.com/concrete/config/../libraries/3rdparty') in /home/lalaami/amimiboutique.com/concrete/libraries/loader.php on line 35

Can anyone help sort this out? What do I need to do?

Thanks!
