Come correggere l’errore 404 della sitemap di WordPress SEO di Yoast

   I just bought the Genesis Framework theme and then installed the yoast seo plugin and activated. I then tried to generate my sitmap and get this same 404 error.

   “Not found, error 404
   The page you are looking for no longer exists. Perhaps you can return back to the site’s homepage and see if you can find what you are looking for. Or, you can try finding it by using the search form below.”

   Does this mean that the theme I got from Genesis is badly coded? Did I waste my money??

     It is highly unlikely, Genesis Child Themes purchased from StudioPress are very well coded. Try deactivating all your plugin to find out if a plugin is causing this issue.

       I had a similar issue after installing Yoast SEO. I deactivated the plugin, then restarted and the URL system picked up and started working as expected. This seems to be related to how the permalink structure is set up as only one of our sites has experienced this issue.

       Thanks for posting!

   The server encountered an internal error or misconfiguration and was unable to complete your request.

     Do you see an error? Can you access WordPress admin area?

   Another easy way to fix the sitemaps is to simply disable sitemap functionality and enable it again…. works for me every time, doesn’t matter what plugins i have installed.

   In Admin, to go SEO > XML SItemaps
   Under ‘XML Sitemap’ uncheck ‘Check this box to enable XML sitemap functionality.’, hit save, check the box again and hit save.

   I already fixed using the first option, how would I know if it’s working already? Should I need to wait for Google’s webmaster report? This is where I saw the 404 error on my site.

     yes you should be able to see your sitemap file in Webmaster Tools

   I replaced the edit files with the XML sitemap fix and completely removed what was there initially. Google webmaster tools has accepted the sitemap however, my sitemap doesn’t show a 404 or anything. Does that mean everything is ok?

     Yes, everything looks OK.

   I tried fixing the 404 error code and now I get the following messege:

   Internal Server Error

   The server encountered an internal error or misconfiguration and was unable to complete your request.

   Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

   More information about this error may be available in the server error log.

   Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

     As the tutorial suggests you added the code in .htaccess file on your webserver? If yes, then simply edit the .htaccess file and remove the code you added.

       I thought I followed to the letter your second suggestion but have the same issue as Melissa. Now waiting for the Webhost for a solution. What about adding a warning in your second solution that it can lead to a 500 Internal Server Error.

       • WPBeginner Support

         You can also revery back by editing the file your modified through FTP. Connect to your website using an FTP client. Locate the file you modified (.htaccess or class-sitemaps.php) and remove the code you added. Alternately, you can also delete the WordPress SEO folder from your wp-content/plugins/ directory through FTP.

    Hi,
    I have wordpress 3.6 with Avada theme and Wordpress SEO by Yoast plugin.
    First I got the 404 error page.
    Then I applied the .htaccess fix without any result.
    Then I applied the class-sitemaps.php fix, now the sitemap returns a blank page.
    What to do?
    Please help. Avada isn’t a crappy theme, I think.

    I’m not sure if I’m doing it write, can somebody explain…. In simple terms are we deleting and replacing the existing code on both options? Or just adding? It’s not clear or does it make a difference if the prexisting remains

    I am new to WordPress and have only begun a using the Canyon theme. I got the 404 message as I was attempting to install a “contact info” plugin. Does anyone know if I just begin at the very beginning again, i.e. go through my GoDaddy account to reinstall WordPress and then reinstall the Canyon theme – might that solve the 404 problem?

    I have two sets of websites (Wordpress Multisite installs) and I have no issues with sitemaps on one of them and I get a 404 error with category_sitemap.xml on the other one.

    I tried both fixes suggested in this post, but they don’t solve the issue. The only thing that works is going to Posts -> Categories – Edit and changing from “Auto detect” to “Always include” on all categories.

    The issue here is that I have over 200 sites, and about 8 categories per page, so it would take too long to do it just to get category sitemaps, even though I could use it….

    Is there any way to mass change all the categories on WP Multisite to “Always include”. I think this would be a solution that would work for everyone.

    Thank you.

    If none of this works try create a file named sitemap_index.xml on your html root through ftp and make sure the permissions are set and the plugin should then take care of the rest.

    I’m not sure which part worked for me, but I found this page because I was getting the 404, too. I disabled the XML Sitemaps in the plugin, then enabled it and checked the boxes to exclude posts (since I only have pages). Now, it is working perfectly.

    During research about a similar 404 sitemap xml feed problem, I found a different reason which I would like to share:

    WordPress adds a 404 header to all feeds if no posts exist in a site.

    It worked for me! Open the class-sitemaps.php file located in plugins > wordpress-seo > inc folder. then find the code around line 79 and replace the old code with this new code:
    /**
    * Initialize sitemaps. Add sitemap rewrite rules and query var
    */
    function init() {
    global $wp_rewrite;
    $GLOBALS[‘wp’]->add_query_var( ‘sitemap’ );
    $GLOBALS[‘wp’]->add_query_var( ‘sitemap_n’ );
    add_rewrite_rule( ‘sitemap_index\.xml$’, ‘index.php?sitemap=1’, ‘top’ );
    add_rewrite_rule( ‘([^/]+?)-sitemap([0-9]+)?\.xml$’, ‘index.php?sitemap=$matches[1]&sitemap_n=$matches[2]’, ‘top’ );
    $wp_rewrite->flush_rules();
    }
    Then, go back to your WP admin page and then go to the SEO plugin > XML sitemaps, and then click the button again (XML Sitemap). The 404 should be replaced with your sitemaps! Easy peasy.

    I’m finding my sitemap gets removed everyday and then indexed again. Here’s what i get every day. http://postimage.org/image/3rb3d8qsr/932c5815/

    I don’t think it’s my theme as i’m using Genesis.

    Not sure but it may be the way my server is configured.

      Has to be a conflict with something else (another plugin or server settings). We are using Genesis on this site as well and do not have that issue.

    Hi!

    Thank you so much for posting this article! With the first fix, I managed to solve the 404 issue for most sitemaps, though there’s still 1 that is showing the error… Any suggestions of what to do?

    I thought about exporting the Yoast SEO settings and reinstalling the plugin to see if that does the trick. Just to be on the safe side: does exporting literally export all settings, even the page/article level SEO customizations OR only the general settings?

    Thanks!

    I know you said the plugin is good, and the problem is in the theme or other plugins, but I tried disabling all plugins and switching to the twenty eleven theme, and the sitemap still gave a 404 error. The only thing that worked for me is editing the htaccess file.

    Hi, I don’t have any problems with yoast seo plug in as I’m currently using it. I just I want to ask if it is better than the all in one seo plug in? I’m just curious because I found out that a lot of blogs in my niche uses it. Which is better? the all in one seo or yoast seo? (I’m already used to yoast). Oh, can I also ask how to set multiple focus keyword in Yoast seo? because there is only one field and I can’t figure out how to set a few more keywords for it. Sorry for my questions I hope you can answer me. Thanks!

    Hmm, I think the second part is going to cause the rewrite rules to be flushed on every page load, which <a href=”http://codex.wordpress.org/Rewrite_API/flush_rules”>the Codex</a> warns not to do due to performance issues:
     
    <blockquote>Because this function can be extremely costly in terms of performance, it should be used as sparingly as possible – such as during activation or deactivation of plugins or themes. Every attempt should be made to avoid using it in hooks that execute on each page load, such as init.</blockquote>
     
    I’m guessing that’s why Joost isn’t doing that by default
     
    Of course, I could be wrong because I don’t know his plugin well enough.

      I was under the same impression when this article came through my RSS. I’m pretty sure going to your permalinks settings page would accomplish the same thing without having to flush the rewrite rules every time the page loads.

         @jonbish Unless you’re running a crappy plugin or theme that DOES flush on every pageload before this plugin gets a chance to get its rewrites in.
