Need to clean vbulletin

[techgsmnet]

I have upgrade vbulletin to latest 3.7.0 version.
Before I have many bugs. And after upgrade they are still present. In profile all still is like in 3.6.8
So I have question- how to restore forum to default, delete all changes in style, all plugins and styles. And live only forums, threads, posts and users?
And after I install all needed modifications, which support 3.7.0 again.

To disable addons, simply disable them all in your ACP -> Plugins and products
To revert all templates go to ACP -> Styles and templates -> Manage styles -> from drop down list select "Revert all templates".
This should do it.

To leave only forums, threads, posts and users, you can use ImpEx to import those things.
