I’ve run into this error and i’m sure many of you has. The plugin in question is this one: http://wordpress.org/extend/plugins/google-sitemap-generator/ and it’s a very popular plugin.
When attempting to view my sitemaps, I receive the following error:
After some research I’ve found a solution and it’s worked on our website along with a few of our clients. Now, in reality, there are two solutions yet I recommend the first one as opposed to the second. I’m not too fond of leaving out the WWW in a domain but to each his own!
Always backup any file that you’re going to make any changes to. Make it a habit!
First & Recommended Solution
- Edit your sitemap-core.php file located at /wp-content/plugins/google-sitemap-generator/sitemap-core.php – do so by using a file manager or an FTP client.
- Search for the following Code:
function GetDefaultStyle() {$p = $this->GetPluginPath();if(file_exists($p . "sitemap.xsl")) {$url = $this->GetPluginUrl();//If called over the admin area using HTTPS, the stylesheet would also be https url, even if the blog frontend is not.if(substr(get_bloginfo('url'),0,5) !="https" && substr($url,0,5)=="https") $url="http" . substr($url,5);return $url . 'sitemap.xsl';}return '';} - Replace the above code with the following Code:
function GetDefaultStyle() {$p = $this->GetPluginPath();if(file_exists($p . "sitemap.xsl")) {return '/wp-content/plugins/google-sitemap-generator/sitemap.xsl';}return '';} - Now Rebuild your sitemap.xml file from the control panel and give it a shot. Let us know how you made out in the form below!
2nd Solutions
- ONLY use this option if your website doesn’t use the WWW
- Locate your .htaccess file and add the following to it:
RewriteEngine OnRewriteCond %{HTTP_HOST} ^domain.com [NC]RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301] - Replace the www.domain.com with your actual domain name
