Hi,

I have a strange problem that is causing internal 404's that I do not understand. The whole thing started at the end of 2017. For some reason the /nl language code gets inserted in url's where they do not belong, causing the 404's . Often this concerns css and javascript files. Today I noticed it also happens on external links in the site. In this case the language code is prefixed before the protocol.

I have no clue where it is coming from. Despite many of these inetrnal 404's have GoogleBot or BingBot as user agent, I do not find these errors back in Google's Search Console of Bing's Webmaster Tools.

When I go to the frontend of the site everything seems to work fine. The links are fully functional and nowhere the languages code is added. Everything works as expected.

I checked my site with Screaming Frog and it doesn't find any 404's.

I know sh404SEF just records what is happening and does not add language codes. So the problem is likely not being caused by your software. However, I really have no idear where to look anymore.

Do you have a clue what is going on here? Are they really internal 404's? Or should they be marked as external?

Best regards,

Joep

p.s.: For some reason I can't attach an image to this ticket. Instead I ran an export of which you will find the contents below:

All these come from the same ip / user-agent:

They are most likely not showing elsewhere because they are coming from CSS and/or javascript files, which are not executed by Google, at least not in the crawling phase, or by ScreamingFrog for instance.

After enabling "Record 404" under "Hits and referrers" if not already done, the referrer page should be displayed in the 404 record details page, that may give a hint.

I have no idea what Google maps would be doing that could cause this however.

There is a link to Google maps on the site. It is normal link written in a custom module. I didn't add that link to any css or javascript.

Thank you for your thoughts on this. Please, close the ticket.

Have a nice day!

Best regards,

The error you show are the other way around: Google Maps makes a request to your site and when that request is displayed, it loads some CSS/js files that have errors in them, or it incorrectly calls upon them.
