I guess you are on windows and use the 8.02 installer.
If that's the case you have to reinstall C::B (just install it over the old version) and chose the plugins you want to install (I advise to install all of them, that means do a full install).
You can disable them from the "Plugins" menu.
If you are on linux and use precompiled binaries install the codeblocks-contrib and wxsmith package(s).
If you have a selfcompiled binary compile either the ContribPlugins workspace if you do it with C::B itself or configure it with "./configure --prefix=</directory/it/should/go/to> --with-contrib-plugins=all" .
