I have a lot of 404 errors in my google's console with strange form. some words added before a code which belong to another link. for example, I have a post with these address
mysite.com/project-15155
mysite.com/project-16155
mysite.com/project-17155
In google's console, I have these 404s
mysite.com/master-xchange-project-15155
mysite.com/master-xchange-project-16155
mysite.com/master-xchange-project-17155
It is a WordPress site. I also have checked "linked from" tab, but it could not useful!
