Hello, I moved a forum to a new server. Unfortunately the data backup I did was currupt so Ive had to build a brand new forum.
However, I copied the forum folder from server aswell. Which file do I need to overwrite to get the new forum looking how the old one did? As I had done alot of tweaking to the theme on the old one & dont want to have to do it all over again,
Thanks

I think the only possible place is ./cache/themes/ but I think everything is stored in the database actually

agggg. In that case I spent 3 hours putting it all back how it was.
But atleast now I know for future.
