Unable to move posts due to 500 error

Hello,

I am encountering an issue by moving a post to a different topic.

When I check the error log:

ActiveRecord::RecordNotUnique (PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_posts_on_topic_id_and_post_number" DETAIL: Key (topic_id, post_number)=(22680, 3) alr

Can somebody suggest me how to fix this error, please?

Thanks in advance!

I found a similar issue that was fixed 5 years ago:

Thanks for your comment @Canapin.

I just checked the topic and I didn’t find a solution for my problem.

Nope, it was a fresh install. None of the content is imported. :slight_smile:
