Hey,

I was working with a site recently who's host suffered a number of issues over a few days, enough to receive a few warnings in GWT - and yes there was a hit to the rankings in the short term. However once their host got their game together the rankings did creep back up, although it took around a month of normal up-time for the ranking to largely recover.

As Greg says i'd definitely ensure you're on a good host, server downtime should be the last thing you need to be worrying about!

All the best,

Stuart

Yep I agree with Dan, unless you really want people to be able to find your lost password page through the search results i'd disallow it as well - actually there is a bunch of stuff you can do to further secure your wp-admin folder should you so choose : http://www.wpbeginner.com/wp-tutorials/11-vital-tips-and-hacks-to-protect-your-wordpress-admin-area/

Ah ok - do you mean that it's showing up in your report of links in Open Site Explorer? If that is the case it is probably because it is linked to from a few pages on your site, including http://inter-italia.com/en/ (under the account drop down it's linked to as 'Forgot Password?')

It looks like this might be an issue with your Worpress theme as it should really be linking to http://inter-italia.com/wp-login.php?action=lostpassword but rather than http://inter-italia.com/en/wp-login.php?action=lostpassword

Best,

Stuart
