I recently logged into one of my sites via FTP and noticed that W3 had apparently duplicated or updated itself. There's a new file in my wp-content/plugins directory w3-total-cache.20130429 that was created on, you guessed it, April 29, 2013.
Now the weird thing is I didn't log into this account yesterday from anywhere. Heck, I didn't even look at the site yesterday.
Any thoughts from experts here in the forums would be appreciated.
Here's a link to a screenshot from my ftp program showing the issue: http://sidwellstudios.com/wp-content/uploads/2013/04/W3-Update.png
