I just checked my website and haven't edited any content or files and have checked with my hosting company to confirm that nothing has been changed on the server and my website is showing this PHP error:

Warning: require_once(/home/******/public_html/cms/_config.php) [function.require-once]: failed to open stream: No such file or directory in /home2/******/public_html/framework/core/manifest/ClassLoader.php on line 57

Fatal error: require_once() [function.require]: Failed opening required '/home/******/public_html/cms/_config.php' (include_path='.:/home2/******/public_html/framework:/home2/******/public_html/framework/parsers:/home2/******/public_html/framework/thirdparty:.:/usr/lib/php:/usr/local/lib/php') in /home2/******/public_html/framework/core/manifest/ClassLoader.php on line 57

It was working fine last night, anyone know how can I fix this?

I'm finding it a bit weird that the error is referring to 2 separate absolute paths /home/... And /home2/... At this point it seems the directory used to be called /home/ but is now called /home2/. I don't quite understand how this could be if your provider sais nothing changed...

But I suppose doing a /dev/build/?flush=1 should flush your cache and point silverstripe back to the correct path...
