 * [@chezterman](https://wordpress.org/support/users/chezterman/) be lSorry to hear
   that. Would it be possible to get access to a staging site to try and work out
   how that is happening?
 * we have one other report by this far have not been able to duplicate the issue.

 * Wow, sorry about the terrible grammar `be lSorry `, was on my mobile trying to
   get responses out quicker.
 * For more clarify, this error seems to indicate our upgrade ajax request handler
   either errored during your upgrades, or is still actively being run be at times
   it shouldn’t.
 * Can you expand on the exact series of events and order. Are you still seeing 
   new errors or are you only seeing them from the time when you ran the upgrade
   itself?
 * Need to narrow down as much as possible when/where in the process things might
   be going wrong.
 * —
 * That said if you are not actively seeing new errors, and your restrictions are
   working correctly, you are likely safe to proceed as you were, but I’d love to
   solve this for possible future upgrades just the same.

 * These errors show me the error.log in the admin folder.
   What happens is that 
   these lines are repeated and that makes the log file become too heavy.

 * [@chezterman](https://wordpress.org/support/users/chezterman/) – Hmm so just 
   to be absolutely certain, your saying these errors occur pretty much all the 
   time (every page load).
 * That’s definitely not ideal, hopefully I can work it out quickly for you.
 * That said the file in question `content-control/classes/Base/Stream.php` is only
   called, or at least should be, during a single AJAX request over the rest API
   after you click the “Start Upgrades” button.
 * It shouldn’t at all run without your interaction, much less on every page load.
 * Would it be possible to get temporary secure access to the site in question so
   I can investigate further?
 * You can [follow this guide](https://contentcontrolplugin.com/docs/getting-started/how-to-get-help/#grant-support-access)
   and submit the token via our [support form](https://contentcontrolplugin.com/support/).

 * [@chezterman](https://wordpress.org/support/users/chezterman/) – As stated in
   email, I’ve put some patches in that should hopefully prevent these notices in
   the future. Look for v2.0.11 and let us know if your still seeing issues.
