Body: <p>Just upgraded to 5.27.3. Tried to upgrade database, got &quot;Sorry, due to an error, we are unable to fulfill your request at the moment. You may want to contact your administrator or service provider with more details about what action you were performing when this occurred.
  Queue runner must be configured before execution.&quot;</p>
  <p>Any ideas what a &quot;queue runner&quot; is and how I fix it?</p>

Comments.Text: I've just restored the whole site with Updraft, then re-followed the CiviCRM upgrade instructions meticulously... Still getting this **Queue runner must be configured before execution** error. Clearly something wrong with the latest CiviCRM for Wordpress code.

  Just upgraded to 5.27.3. Tried to upgrade database, got "Sorry, due to an error, we are unable to fulfill your request at the moment. You may want to contact your administrator or service provider with more details about what action you were performing when this occurred.
  Queue runner must be configured before execution."
  
  Any ideas what a "queue runner" is and how I fix it?
  
  Thanks
