wrap-function, wrap-raf, contextual-ee affixing on web pages

Question

I am experiencing a strange behavior on my website. I recently found on webmaster tools that, it found crawl error 404 for many webpages on my website. I could not understand how these pages are created because all of the 404 pages contains these few words at the end

wrap-function, contextual-ee, wrap-events, wrap-raf, wrap-timer, wrap-xhr

The pages are created by affixing one of these word at the end of normal working pages.

For example the 404 pages are:

mywebsite.com/normalpage1/wrap-funcion

mywebsite.com/nromalpage2/wrap-event

mywebsite.com/normalpage3/wrap-timer

I am using Wordpress self hosted blog.

An update to the Browser agent was released yesterday afternoon which contained a fix for this issue. For URLs that have already been crawled, it may it may take some time for the bot to stop attempting to crawl them, but it will eventually resolve on its own.

To confirm that your site is running the latest version, please search for "372.min.js" in the HTML source. If you have currently running application agents, you may need to restart these agents for the change to be picked up.
