Seem to be getting quite a few of these logged in the ACP.

Had this again just now. Marking all forums as read on my site.

The only thing that I can see that would cause this is if the pertinent entity was missing table from its structure. I can't see why that would be the case unless an add-on was erroneously overwriting it, and I haven't been able to reproduce this locally.

Is there anything specific I could search for in the addons that might indicate this could be the cause?

 

[Jeremy P]

If it is an add-on, presumably it extends the \XF\Entity\Node and/or \XF\Entity\Forum classes or has an entity_structure code listener which either has those classes as hints or no hint at all.

I know this has been marked as Not A Bug, but I'm still getting these errors, and have no idea what's causing them:

Since I can't reproduce this or see how it could occur, and nobody else has reported it, I'm inclined to believe it's not a bug in the core. If it still occurs on the default style with all add-ons disabled and you're comfortable providing server access, feel free to flag me down in a ticket and I'll take a closer look.

And if anybody else runs into this, please let me know and I'll re-open the report.
