Clayton James on "Crawl error - 404 Page not found"

Hello,

I'm having an issue with crawl errors. For some reason, all of a sudden I started having many pages ( way many than the actual website's post count )being indexed by google and appearing as not found - 404.

The screenshot from the webmaster tool can be found at http://ptscr.com/bsn2rv
So basically the first words are my post names and then i get that WP_PB_URL_AUTHOR/etc generated automatically.

I've got no idea what that could be, I tried to search for those errors but couldn't find any info. Curious that I'm only getting this errors on the Desktop version of the website and nothing on the Smartphone.

Any help would be very much appreciated.

Vic

Are you using this plugin? https://wordpress.org/support/plugin/adsense-box

Hello James, thanks for your reply.

And yes, I am using that plugin. Has anything to do with it?

I would suspect it's possible. See line 164 in the plugin widget.php file: https://plugins.trac.wordpress.org/browser/adsense-box/trunk/includes/widget.php#L164

You may want to post a support question directly to the plugin dedicated support forum and see if the developer thinks it's anything to be conceed with or not. https://wordpress.org/support/plugin/adsense-box
