Sound strange no chippers suite.Maybe you are using the old Apache?
On the main home of Webuzo in the left search bar digit Apache, you will see two Apache listed.You should install Apache 2.4 that is the most updated, once installed you should make default or you should check the check box to use as default.
Try to see if in this case Chippers are presents, if not you can try to add the relative line always after do a backup of the configuration so you can resume in case of any issue.
