Help Please

ERROR:
The cache directory is currently not writable! In order for PunBB to function properly, the directory named cache must be writable by PHP. Use chmod to set the appropriate directory permissions. If in doubt, chmod to 0777.

The avatar directory is currently not writable! If you want users to be able to upload their own avatar images you must see to it that the directory named img/avatars is writable by PHP. You can later choose to save avatar images in a different directory (see Admin/Options). Use chmod to set the appropriate directory permissions. If in doubt, chmod to 0777.

any help welcome
