Many Links Broken
To my tens of thousands of readers.
I have discovered that all links to posts and documents internal to this site are broken. I had to move the site from its previous server to the present location and the URLs to site-internal locations all point to the previous server. URLs to external servers still work, so long as those servers are still up and running.
I’ve also noticed that funny characters have popped up in the text again as they did when the original site had problems.
I have a day job now and don’t have time to fix these problems.
If a post has a URL that links to a previous post you’ll have to track down the previous post and open it directly.

What operating system are you using? Is it possible for you to log in via the command line? What is your hosting provider? A search-and-replace could correct this, but it is done in different ways in different OSes.
