Poll thread type without a poll

[Andy.N]

Affected version

2.2.15

Got this error from a thread without a poll. When I went to change thread type, it shown as currently a poll. After changing to discussion type, the error still persists.

You might want to try rebuilding thread data (rebuilding post positions is not necessary), as it seems like somehow the thread record has become inconsistent with the first post of the thread.

 

[Andy.N]

Thank you. This has been resolved with your tip.
Changed the thread type to discussion then rebuild thread data to clear this up. No more error.

Will leave this open to see if we get further reports, but it's not immediately clear how this would occur short of an add-on or direct database manipulation.

We also encountered this message after we upgraded to 2.2.15. It appears to have occurred in cases where the first post of a thread was deleted. It looks like all the threads that have this issue had a first post date from when we used to run on vBulletin (since deleting the first post deletes the thread in Xenforo).
