I moved Misssing Profile Picture options from How to Change User Profile Picture.
Because I was careless, before I split it, I marked one of the soon-to-be-moved posts as the solution. @moin kindly and privately pointed out that this was not, in fact, a solution to the OP. So I split it. Now the new topic still has the no-longer-in-the-topic post marked as the solution and in the new topic, if I try to mark that post as the solution, I get a 500 error.
To reproduce:
- create a topic with some posts
- mark a post as the solution
- move that post and some others to a new topic
- now the original topic has a post that’s not in the topic marked as the solution
