If you got the following error in WordPress when saving, auto-saving, or commenting on a post :
Warning: fsockopen() [function.fsockopen]: unable to connect to submissions.ask.com:80 in /path/to/blog/wp-includes/class-snoopy.php on line 1150 then keep reading ðŸ˜‰
The answer is at the WordPress Support website.
Bottom line: it might be caused by the Google XML sitemaps module (great module to generate an XML sitemap) which can’t ping ask.com.
Solution : Stop pinging ask.com by going to options->XML-Sitemap and uncheck “Notify Ask.com”, “Update Options” and voilà.
