Google webmasters reports 'undefined' in URLs causes 404's (7 posts)

    I keep a pretty close monitor on Google Webmasters for errors and such in my blog. However, about 10 days ago they started reporting 404 (not found) errors on the blog. The count increases every day and is now up to 601 404's. The URLs all have "undefined" as the last piece of the it:

    http://..../2009/01/app-review-alphabetic-by-no-monkeys/undefined

    I've been searching for the source of the problem for days and can't find it. When I go to the referring page, view source, then search for "undefined" there's nothing there. It is likely being generated upon pageload and appears to only happen with Google (since I can't find it using FF, IE, Safari).

    If anyone has ANY clues on what plugin or function it may be I would greatly appreciate it.

    Thanks,

    What custom permalink structure are you using?

    I have it as: /%year%/%monthnum%/%postname%/

    So, the undefined is coming from somewhere else, like a plugin (??). But I just can't figure out which one.

    I'm seeing this same thing. For every page/link on my site, for some reason google is trying to look for: http://example.com/page/undefined and getting a 404. =/

    Any luck finding the cause netslacker? I can't figure out where it's getting this link from... it's not in the source for the pages.

    I started having an issue that keeps getting worse and has not taken the whole site from google....

    http://fromthecrowd.com/wordpress/?cat=112 404 (Not found) 5 pages Aug 20, 2009

    I do have permalinks... post number/post title

    so what was:

    now has to be:

    http://fromthecrowd.com/?p=984

    For google to not classify my entire site as a 404

    http://www.fromthecrowd.com/984/concert-photos-green-day-august-22-2009/

    the site was perfect and getting alot of google bot hits but since this 404 business has halted.

    If I go back to basic permalinks (?p=XXX) google is fine, but now that I have permalinks those titles don't linkl up right, so I am having to re-direct until this gets fixed.

    Any ideas?

    Just thought I would chime back in and say, I finally found something in the google webmaster tools forums saying this is a "google" problem.

    Basically, google is trying to crawl some javascript code. It seems engineering has fixed the issue, as people (including myself) are starting to see 404 counts go down.

    So, you should be able to just wait it out.

    Thanks!

    I seem to be having the same problem on one of my blogs but not on the other almost identical blog. Any luck with this??
