I recently moved to a new server, and in the process I managed to deploy it on an Apache without mod_rewrite enabled. This meant that all pages but the front page were unavailable, which of course I didn’t notice because I didn’t check more than the front page. This is why I don’t have a job as a sysadmin. The only reason I figured out that something was wrong was that my Google analytics figures had fallen off a cliff.
Normal service ought now to have been resumed.
