Just wipe out the directory structure but import over the database and retain the forum posts and members?
But the forum file structure would remain the same, correct?No.
One possible course of action though would be to upgrade to 1.2 then use the XenForo 1.2 importer to selectively import users and other content into a new database.
Nothing in particular. Just thought it might be easier to start from scratch than worry about all the template edits and whatnot I've got going. Just a clean install and start adding back in the addons from there.What is it you are trying to do exactly?
Why not just upgrade your forum from 1.1.5 to 1.2.0?
