The feedback I'm getting from my users is that they cannot get rid of the screen appearing constantly, and they are likely to have accessed the site directly.
I'm quite certain it's clean. I did a thorough search of the files I copied over, and the majority of files were deleted and reuploaded from the offline development site.
We came back online on the 17th December. Since we've been getting killed in pageviews and visits according to google analytics :( The site has been online for about 5 years (with one domain name change this September) so I thought we were well established, but it looks like pages are dropping off google.
