Where can I find the delete log for posts and topics? Thank you.

Are you referring to the error log? If so you can find that in your WordPress admin under Forum > Toolbox > Error Log

The log can be emptied at the bottom of the list

If this is not what you're looking for can you be more specific?

I'm looking for a log on topics deleted by users as well as posts. 

I'm sure someone will correct me if I'm wrong, but I think the only way you can find a deleted topic is if you have a backup of the database from when the topic was still active.

You can easily look at the edit log of a still active post however. Find the post and you should have a 'View Edited Posts' button in the post action section above the post content.

Sorry if that's not very helpful, and as I said I'm sure someone will correct me if there is a way to find deleted posts (at least title I'm guessing)

I'm not trying to find the actual post but the log that says who deleted that post and when.

We do not currently keep such a log. We DO have a ticket open to discuss and potentially add such a feature.

Okay. Thanks for the help.

I hope to work something similar after this release... no promises..
