My site is still broken and I can’t find anyway to get it back. I was hoping to get some idea on how to fix this issue, but I’m surprised not to have heard anything. My only other option is to go back to a backup from October, which will mean losing a lot of content and I’d rather not do that if possible.
Since posting this, I’ve tried looking through all the main code looking for references to W3 Total cache with no luck. I’ve also reverted back to the default theme, no luck. I’m out of ideas.
