Fatal error: Call to undefined function wp_using_ext_object_cache()

    Hello – I have done a manual upgrade of wordpress and am getting this error, for both the query.php and option.php pages.

    If I replace all the files/folders in the wp-includes directory, with clean versions from the install, then my site appears as normal. But after a few minutes or sometimes several, the error comes up again.

    Any ideas on what might be the issue(s)? Let me know if there’s anything I can do to correct the problem.

    Thanks, Yuri

  • Do you have caching enabled on your site? Empty/disable the cache and see if that provides a cure.

    Dumb question > where are the cache settings?

    If you don’t know where they are, you’re probably not running a caching plugin, unless someone set the site up for you of course. Have a look at your active plugins to see if there is one vaguely sounding like a cache.

    Of course it might not be the cause of your issue. I’d be inclined to overwrite all the WordPress core files, not just the ones in wp-includes.

    No, am not running any caching plugins, just aksimet. I’ve overwritten all the core files, and have now reinstalled wordpress a few times, with no success. It’s always the same, after I reinstall the site appears fine, and then I get the error after a few minutes. Very frustrating. Could it be a server/hosting issue? I’m using Hostway, and have been for years.

    Try to enable wp_debug from wp-config.php, wordpress will provide information if any error from your themes

    Hi all, this was the first result after googling the error. I also received a similar error when trying to install WooCommerce. I was attempting to install it on my local copy of WordPress. The solution, in my situation, was upgrading WP to the latest 3.8.1. I assume the latest plugin is incompatible with older versions of WP.

    I’ve seen this with other WooCommerce issues – an older version of WordPress. Just upgrade WordPress and that should solve that.
