Fatal error: Class 'Cache' not found

My hosting company restored my site from their yesterday backup. There where issues with the restoration, the site didn't load and the error log generated:

PHP Fatal error:  Class 'Cache' not found in ... classes/ObjectModel.php on line 1835

I looked for the issue and stumbled upon that thread with the fix to delete "class_index.php" in cache folder.

That fixed it, it regenerated the file and the site was up.

The thing is that my site now looked like from a month ago, so much work and bug fixes had disappeared, but other things like module installations where present. I have no idea what's going on, I have restored before and haven't experienced this error with the file or that the restore looks something like from a month ago.

I didn't touch or restore the db, that one is current, so I didn't have to.

It should be easy to check in your files whether you can find your fixes there. If they aren't there that suggest that your provider accidentally set back an older version.
