Hi, sorry but that is not possible, you had other problems. The plugin just write into a cache the page content, it cannot “crush” a site. Probably you had problem with wp-config.php modifications or like, there is nothing in the plugin code that can destroy a site and which requires a complete restore.
Stefano.
Cache in any kind of site or CMS can cause a site to become unresponsive, it can become corrupted. Normally a simple manual cleanup of the cache folder can fix it.
The plugin has been completely removed. then I installed the plugin again. Now the site is working fine.
@dorogoi,
Since the plugin does work in your site after you reinstall it, it would be nice if you would consider changing your ratings to something higher.
Kind regards
