At some point, many of us prune older threads in order to keep our database size manageable.
The most obvious way to delete a large forum (containing many threads, subforums, subsubforums, etc -- you get the idea) seems to be this:
AdminCP -> Forums & Moderators -> Forum Manager
That seems to work for smaller forums.
Unfortunately, according to my own experience and several other reports on this site, vbulletin.com, and others, this doesn't work for anything big. When I tried to delete a large forum representing just over half of my post table, total MYI file size ~2 GB, the script ran for almost 4 hours and then failed silently. It did unsubscribe people from the forum (and subforums), but not from the threads, nor did it delete anything (or, if it did, the amount of deletion performed was negligible). I found no trace of any error messages.
vBulletin support suggested that I go in and delete the subforums individually by hand. Unfortunately, there were over a thousand of them, and the interface is clunky at best. Spending the next 2 weeks deleting forums for 8 hours a day just wasn't going to work out.
To automate this job, one should instead start go to:
AdminCP -> Threads & Posts -> Prune
And prune threads. In our case, with a ~5 GB database and 4 GB of memory, I could process about 2000 threads at a time with successful completion. For me, this meant stepping through the thread 50 to 100 days at a time through its history (your rate of thread addition will likely be different, but the same general approach can be applied).
Once the forum I wanted to remove had less than about 10,000 threads in it (including in subforums), I was able to remove all of the rest of it the officially prescribed way, using forum manager.
And that's it! Sounds pretty simple, but if I'd run across a post containing this information earlier this weekend, I'd have saved hours of my time.

It may already be empty. Did you ever have it turned on and use it? If not, then there is nothing to do. See if there are any rows in your postedithistory table. If there aren't any, then there is nothing to do.
edit history is just showing an edit date on the bottom of the thread (table editlog). Post edit history is storing the contents of the posts as it is edited so you can go back and see what has been changed (table postedithistory).
can you try it yourself here
go to Article Options or Thread Tools as it is in 3.8 translated and choose edit thread > perform action
and click save changes to confirm editing ( do not change any thing i dont want Birched hate me )
do it again go to Article Options you will see this
hahahah i saw it now when i changed language from arabic to english
its in moderatorlog i think not postedithistory table
so how can i remove them
and what will happen if i choose to empty moderatorlog table
i want to thank you so much for your interest
its big honor to me
You may delete your moderator logs in admincp > statistics & logs > moderator logs > prune moderator log. If you prune them, you just won't see things in Edit Thread where it shows the moderator log (like in your image).
Why are you trying to do this? You are not going to be saving a bunch of database space by the actions you are talking about here.
its not about space
it works like a charm as you said admincp > statistics & logs > moderator logs > prune moderator log
thank you so much
and i hope i didn't bothered you
