It seems Google Tries to crawl pages I never created and gets a 404 error, but it thinks or maybe somewhere in my code, google thinks there is a second page.
For example, I have this page http://ecsimplified.com/portfolio_category/tops
But not this page that google found a 404 error: //ecsimplified.com/portfolio_category/tops/page/2/
Since I didn't create this page or link to this page, why would it find this error?
