I recently shifted my web-server. During the transfer I forgot to disable the caching first. And after the shifting, as because the root name is changed the plugin cannot be reactivated in my installation. It cannot find the sample file as the path is changed.
The error is:
plugins/wp-super-cache/wp-cache-config-sample.php) does not exist.Verify you installation.
Cannot continue... fix previous problems and retry.
Can't find, where to change in my database. :(
