I experience strange behavior on my website. I recently found in webmaster tools that I found a 404 crawl error for many web pages on my website. I could not understand how these pages are created, because all 404 pages contain these few words at the end
wrap-function, contextual-ee, wrap-events, wrap-raf, wrap-timer, wrap-xhr
Pages are created by attaching one of these words to the end of regular work pages.
For example, 404 pages:
mywebsite.com/normalpage1/wrap-funcion
mywebsite.com/nromalpage2/wrap-event
mywebsite.com/normalpage3/wrap-timer
I use my own Wordpress blog.
