How to close a topic by API?
I would like to close a topic from PHP.
For this, I tried this:
WPF()->topic->edit( [ 'topicid' => 1, 'closed' => 1] )
... but this does not close it.
I can't find a solution, but I think this should be called also:
wpforo_clean_cache( 'topic', 1 )
Do I have to call a SQL UPDATE statement directly, or do you have a function for me, doing this?
