I have three 404 errors and am hesitant to just dissallow in file editor as I'm not sure what they mean and the first one makes no sense at all. Here is a screen shot of the first two:

The first one reads "affordable-hunting-and-fishing". My website address is affordablehuntingandfishing.com, so I'm not sure why this error would come up. If I click on the 404 error url it goes to: http://affordablehuntingandfishing.com/affordable-hunting-and-fishing

The second one reads "creek-fishing-videoshttp:/". I can't imagine where google would be picking up the http:/ at the end of videos. This one appears to be a good candidate for dissallowing in file editor but want to make sure. I do have a post affordablehuntingandfishing.com/creek-fishing-videos.

There is a tab that reads "other" next to "not found" in the webmaster tool that this 404 error show up in:

It reads xmlrpc.php, I have not idea what this could be. If I click on the url it brings up: http://affordablehuntingandfishing.com/xmlrpc.php

Would greatly appreciate thoughts on these. Thanks so much.
