I came to do some minor changes on my sites under a multi-site install today and all the wp files and folders have vanished from the server - The database is still in place but the wp files and almost all other files -gone.
There was a big traffic spike yesterday meaning that the analytics code must have still been in place then.
Could this be a malicious attack ? What else could cause this?
More constructively - I'm reinstalling WP. Question is:
Can I get the new install to use the existing database ( from the vanished in stall) and if so what are the steps to doing this?
