WordPress Not Pinging? – Here’s To How To Fix It!

It’s been a funny old week since I updated to WordPress 2.9, don’t get me wrong the new update is fantastic and some of the new features are extremely useful to use, but, and this is a big but, after installing the update, every time I made a post or used a ping back or trackback my WordPress blog would not ping or send pingbacks to other sites!

But now since making a tiny little tweak to the file “wp-includes/cron.php” I’ve fixed the problem!

If you look at the original code for cron.php you will find the following code:

$cron_url = get_option( ‘siteurl’ ) . ‘/wp-cron.php?doing_wp_cron';
wp_remote_post( $cron_url, array(‘timeout’ => 0.01, ‘blocking’ => false, ‘sslverify’ => apply_filters(‘https_local_ssl_verify’, true)) );

You will notice that I have made a bit bold! This is what you need to change, change this to 1 so now it should read:

$cron_url = get_option( ‘siteurl’ ) . ‘/wp-cron.php?doing_wp_cron';
wp_remote_post( $cron_url, array(‘timeout’ => 1, ‘blocking’ => false, ‘sslverify’ => apply_filters(‘https_local_ssl_verify’, true)) );

Now you should find that you pings are now working again, hopefully, I checked mine via the Ping Optimizer plugin and the log on the plugin confirmed a ping status!

Please remember before using this tweak, back up your original “wp-includes/cron.php” file, just in case, you never know ;)

    Book marked, tweeted and wrote a post linking back to help spread the word. How do you check your pings like you were, what did you look at to determine there was even a problem? How do you check if your site is giving pingbacks to other sites properly?

      Thanks for the post and link back, I use the Ping Optimizer to check my pings and it’s log wasn’t showing any pings on updates to posts etc, it is a handy plugin it only pings when you make a new post instead of pinging every time you edit a post.

      I can’t take all the credit, a friend of mine mentioned the word “Cron” so I looked through the WP files and found a file to check out and then changed a setting! It wasn’t the first file I tried editing ;)

  • Mike

    I had some serious headaches with 2.9 – mostly conflict with plugins, but I’m going to have to see if I’m having this problem too.

      So far, plugins are not a problem, themes yes! But not plugins :lol:

      • http://www.goblogger.net Isaac

        I think I’ll wait for the 2.9.1 . I hope they will fix everything by then, and the plugins will be updated and ready for the 2.9 ;-)

    I have been having trouble with one of my new blogs. Let’s see how it changes..By the way, Karen..any idea about this other line in the code:

    $crons[$timestamp][$hook][$key] = array( ‘schedule’ => false, ‘args’ => $args );

    Schedule is set to false? Is there something wrong here?

    • http://blazingminds.co.uk Karen

      Leave that code, as far as I know it used when you schedule a post ;)

        Aargh..How did I confuse scheduling with pinging! :O

    Could you tell me where I find the cron.php file please, so I can edit to see if that fixes my problem.

      Hi Sonya, I did mention in the beginning of the post that the file is located at “wp-includes/cron.php”

    Hi, I tried this and got it to validate for a few minutes and then poof. Back to 404. Very frustrating. (As you can see below, my feed stopped working Christmas.) Think it’s a plugin conflict issue then?

    • http://blazingminds.co.uk Karen

      Could well be, if you are using WordPress try changing your feed to summary instead of full text, sometimes feedburner doesn’t like it when coding is added to a blog post!

  • http://www.copywritingmaven.com Roberta Rosenberg

    I’m sure I’m missing something here, but FB won’t let me change the feed setting since it can’t find my URL. Stymied.
    .-= Roberta Rosenberg is hoping you stop by and read MavenTweets for 2009-12-25 =-.

    • http://blazingminds.co.uk Karen

      hmmm, if you have a plugin that forwards your feed to feedburner, disable it and then write a new post, then see if your normal blog feed has the updated post in it, failing that, check you are running WordPress 2.9.1 if not upgrade and then see if it work. Failing that I’m not too sure, so anyone else reading this post got any ideas?

  • http://www.copywritingmaven.com Roberta Rosenberg

    Thanks for the assist, and I tried what you suggested. Nada. I’m already on 2.9.1
