My host moved servers (without informing me) and all of a sudden my blog (http://vincent.van-wylick.com/blog/) no longer loads. I realise that it's his fault, but he is a friend and frankly knows nothing of WordPress and how it works. I myself know little about the server-side of things.
I need some troubleshooting so that I can start and fix it. The server runs on Apache, Mysql, and PHP, though I don't know which versions right, not too old for WP anyway. The migration was, according to him, a direct one, and nothing in terms of permissions, databases, etc. should have changed.
I tried re-installing several times, as well as emptying plug-ins and themes (except the default one). I just upgraded to 2.2c to see if that would fix it, but to no avail. When I try the we-admin/upgrade.php, it just downloads the .php file. Same with install.php.
Any advice? I'd be happy to give someone access to my ftp server if that would help.
