Help me please redirection and cache problem with my site.

Help me please redirection problem with my site.

When I place; URL instead of going to the home page, go to this address This address no longer exists, the category "Uncategorized" was deleted.

This only happens on Google in the browser works well.
Apparently it's a problem of cache memory, poruqe in google there is an arrow that señaña "in cache".

I am using WP-cache, and memory have emptied, but when I search on google, again it appears non-existent address. (

Alguen know I can do?

thank you very much to whoever answers
