Hi,

I’m using the 2.5.1 version of Discourse and get a “500 Internal Server Error” when approving a post in review.

Here is the error in /logs:

Message (7 copies reported)

We are experiencing the same issue in the same circumnstances as described by Camille.

So we tried to edit the post first, and then tried again to approve it, but the problem persist.

Any solution available?

Thank you

I’m still having the same problem with the v2.5.2 +2 version.
It seems to happen to the posts triggering the auto silence fast typers on first post option.

Hi @CamilleRoux!

I couldn’t reproduce this locally so maybe I’m missing something. Does this happen when you try to approve any queued post, or only for a particular one?

I’ve no other message in review… What can I do to give you more info?

I just set approve new topics unless trust level the max and now I get a 500 error when I post a new topic. It seems to be quite the same error:

ActiveRecord::StatementInvalid (PG::InFailedSqlTransaction: ERROR:  current transaction is aborted, commands ignored until end of transaction block
)

Can you enter the container and check the PostgreSQL logs for an error around the same timestamp?

Thanks, that really helps!

Did you were tracking the beta branch at some point and then switched to stable? The private_message column was added in v2.6.0.beta2, but the commit is not included in v2.5.2 +2. This is the commit:

https://github.com/discourse/discourse/commit/92b7fe4c62094275c5dd09b1f3dac5c5cbcad1c0

Arf… Yes I did that, my bad. Thank you very much!

Do you know if the next stable version will be release soon?

That is completely unsupported and will result in a broken Discourse. Revert back to the default tests-passed or beta ASAP.

We cut a “stable” version approximately every 6 months, the next one is tracked on Discourse Version 2.6
