Mass close all posts in one forum

[Robert Fogt]

My old vb 3.8 guest posted messages cannot be replied to in 5.0 cloud, so I need to close them all. But there are over 10k of them, seems to many to do by hand.

Any way to close all the posts in a certain forum in the admin panel? Or through a support ticket?

You can close all the ones that are on a single forum thread listing...tick all the boxes and then select the close option from the moderator tools at the top.

Appreciate for 10k that's still not practical, but there's no other way to do this I'm afraid.
