Thanks to my good friend Annette and her staff at Hosting Matters my site has been freed of the graffiti left behind by whatever vandal stopped by.
It turned out that there wasn’t any serious damage (as far as we can tell). That little tab reading FORCE at the top of the page led to a newly-created page incorporated into the blog and a new Administrator was created in the user panel. Once identified it was easily removed and corrected. I’m lucky it was just vandalism.
If you need a good webhost I strongly recommend the nice people at Hosting Matters. They’re in Florida but they’re very responsive even to customers 5,000 miles away.
