It seems you did not install the contrib-plugins package.
Hooo, yup, you are right, i try install contrib-plugins downloaded from homepage (inside fedora package), but when i try it, i got the message:
--------------------------------------------
Next package is containing an invalid signature:
/ home/victor/Descargas/cbrpm/codeblocks-contrib-8.02-0.fc8.i386.rpm: Invalid Signature (NOT OK (no key): / home/victor/Descargas/cbrpm/codeblocks-contrib-8.02-0 . fc8.i386.rpm: HeaderV3 DSA signature: NOKEY, key ID 9b0c43df)
--------------------------------------------
And ask me to continue instalation, but when i press continue button just stop, i think is not installing, where can i download another rpm package including contrib-plugins?.
Thanks again

Vic.
