Lost myspiders visits

Hi,

I’m really happy with my wordpress. I was my first CMS/blog system and I recommend it to everyone asking me. In overall everything runs just fine. The only problem I’m having is that when looking to my statpress plugin, it has lost spiders visits since 1 week. I’ve searched forums and some people say it can be a robots.txt problem. The thing is that I havent changed it since like 2 months. Here you have it:

User-agent: *
Disallow: /guadiana
Allow: /

I don’t really understand why it happens. Last week I removed some plugins but it seems to me that it can’t be the reason since robots.txt hasn’t changed.

Anohter strange thing, is in google analitycs I’m getting like 40 search engines visit per day. So I don’t understand this contradiction.
