Luckily, the fellow who helped me at my hosting support uses wordpress for himself, so he was able to figure out that configurations were wiped clean, I think.
I was getting this: Fatal error: Call to undefined function: wp() in /home/corinna/public_html/home/wp-blog-header.php on line 16 when I went to http://www.stamptopia.com
Not a good thing, when I run a tiny direct selling business and I sent out a newsletter to my customers telling them to go to my site, eh? Ohh... how Fate and I don't get along!
I use Fantastico De Luxe to install and upgrade WP and my hosting service does NOT support it.
I have no clue what to look for..
