WordPress 4.3 Stability Issue & Fix

Nemanja Aleksic

The latest 4.3 WordPress release has caused stability issues for some WordPress users. Although it’s not wide-spread, the cron bug has been reported to cause database issues and high site server CPU load.

Tell me more about the bug!

Reversed arguments for the scheduled task to split terms could cause the database to balloon in size in certain cases. Here’s the ticket with more detailed information:

How can I fix it?

The solution has already been found, and it will be deployed in the 4.3.1 release. In the meantime there’s no need to worry, we got your back!

No, not literally.

Peter Wilson already released released the hotfix plugin on the WordPress repo. You can use ManageWP to instantly deploy it on all of your websites. Just follow these simple steps:

  • Go to Manage >Plugins & Themes on your ManageWP dashboard
  • Check Activate, and check all of your websites on the right
  • Search for “wp33423 hotfix” in the WordPress repository
  • Click Install
  • Celebrate, preferably with a victory dance

hotfix

Once the 4.3.1 WordPress version has been released, this plugin will deactivate itself automatically, and you can then use our Manage Plugins & Themes to completely remove it from your websites in seconds.

UPDATE: The 4.3.1 release is live, you no longer need to apply this fix – just use the ManageWP update widget to run the WordPress core update on all of your websites.

    That hotfix option is awesome. Curious, is ManageWP monitoring the Chrome 45 / WordPress admin bug? This bug is potentially affecting 1000s of WP admins.

    You could push out this hotfix / plugin:

    Wonderful, because this is the sort of thing that makes maintenance customers feel warm and fuzzy about having someone else who possesses their spines..um..has their backs. 😉

    That’s ManageWP: applying WP fixes before WP does. Love it.

    Perhaps I missed it, but should this be applied only to 4.3? I’ve got only 2 sites with 4.3 but a couple dozen at 4.2x on same server where MySQL was affected.

    Your instructions for the hotfix say to INSTALL it and then “celebrate”, but shouldn’t we INSTALL it, then ACTIVATE it on ALL sites, before we do our dance? 🙂

    On a couple of my sites, I get this error whenever I try to install/update anything (WordPress, plugins, etc):

    Downloading update…

    Download failed.: error:0D0890A1:asn1 encoding routines:ASN1_verify:unknown message digest algorithm

    Installation Failed

    Why is this…?

    Some of my domains have not yet updated to version 4.3. They do this automatically. Should I install the plugin before the upgrade?

    Hope I’m wrong, but I upgraded a site from 4.2x straight to 4.3.1 this morning and now I’ve got high memory issues. The only site on the VPS and the only change made to the site. Be advised…

    The 4.3 / 4.3.1 auto upgrade whacked my database.

    Once I get my site working properly again, I am shutting off automatic upgrades.

    So tired of this foolishness WordPress core team!

    As of today. I’ve got 4.3.1 on boards and the bug is still there. Reinstalled 4.3.1 for the eighth time (just now) and bug is still there. Installed and activated wp33423 hotfix and that didn’t fix it either. I’m using just one platform.

    ???
