Hello Daneil,

I’m Mohammed: the Toolset support team leader. I’ll give my best to help you.

To be able to work on this issue, I would like to replicate the issue on my local machine.
So, it will be very helpful if you provided the exact steps to replicate the issue.

FYI, this may be a conflict with other plugins because I see that you have many plugins installed.
So, you can disable all non-Toolset plugins and activate a default theme (Twenty seventeen) and test if the issue still exists.

Thanks.

For the record, I'm seeing the exact same errors on two of my sites running Toolset. I'm not sure what triggers the error though.

Hi, I saw your earlier answer to disable plugins and activate default theme. Unfortunately, I can't do that with these live sites. When I have time, I'll see if I can set up a test site to replicate the issue and will respond back.

If this helps, both site are running Genesis theme but with different child themes. My error logs show the error occuring very frequently, about 4-6 times an hour on average.

This error was due to Jetpack performing background synchronizations.

We add a fix for this error in the Types version that has been released yesterday.

Can you update to 2.2.17 and re-check?
The particular error should not exist anymore.

Note that only this particular errors has been addressed.
You may still find errors in CRED screens related to Toolset.
If so, please open a new report for any other kind of error you may find.

Thank you!
