To answer @Full30, I agree that topics don’t need to be closed so soon.
The topic that you mention was automatically closed because you marked a post as the Solution. For topics on Meta, they’re closed 30 days automatically after a solution is marked, because it’s assumed that the problem is solved and there’s no need for further discussion.
Other topics in Support > WordPress remain open for months and years and so on.
I think it would make sense to ask moderators to reopen the original topic and merge your second topic there, since it turns out that your issue is still unresolved.
If @community-moderators could merge these two topics, and reopen the discussion, that would be helpful:

Thanks in advance.
