I have 4 other domains currently on my hostgator account, all using wordpress and working great. I recently added another domain, but the install isn't working. I've installed it, and it doesn't give me any errors during, but when I try to login in @ domain.com/wp-admin, it gives me a "500 Internal Server Error nginx/0.8.52", then when I check my domain, it hasn't changed to wordpress, it's still on the index.html page I created. After WP is installed in Fantastico, it appears to be working correctly in my file manager, everything looks in order there I can even upload themes etc. I've tried uninstalling/reinstalling and clearing my cookies. Any ideas?
