Hi, I could do with some help on this.

It starting happening a few days ago and hoped upgrading to v4.7.2.1 (on PHP 7.4) would resolve the issue but it hasn't.  The following error is appearing many times within the System Logs:

 

Access Information has been updated.

 

Seeing a few third party add-ons related here to this, I would advise upgrading or disabling those listed there and testing to see if this continues. Please let us know how it goes.

I've rebuilt my test site with a copy of the live DB and Files. 

Once the errors to repeat on this new site I will start disabling the add-ons and see were it gets us.

Please let us know the result of this, and if you then still have problems, we can of course take it from there

Now I've got no further errors in both the live and test copies!

I will keep watch and report back again later.

I can confirm that this is a valid bug which will happen under specific circumstances.
It's logged now to our bug tracker.

Thanks Daniel

Hope you can identity this specific circumstance as I'm not seeing the error since Marc had a look.

It happens only when gallery albums appear in the stream AND when the cron option is used.

This item has now been resolved on the latest 4.7.5 release of the platform. If you are experiencing issues once you have upgraded, please let us know.
