This site was shut down for a few days due to a malware infection. Both Google and my host provider flagged the site and alerted me to the problem, which was ultimately solved by deleting the entire site, re-installing fresh, and restoring the database. As a result the site is sporting a new look – which I am trying to decide if I like or not.
Anyway, it was a learning experience, and what I learned was a) backup regularly and b) restoring a wordpress site is not hard, if you follow a).
If there are any missing graphics or broken links as a result of the re-build, please let me know.
