I've set up multiple products on a new Bugzilla installation, but only one of them is used. On the "new bug" page, it is automatically selected and there isn't even a drop-down list to pick one of the others.
When editing a bug, the drop-down list for Product does appear, but has only one entry.
Presumably the other products are misconfigured in some way, but I can't see how. I've never done this before, so I have almost certainly done something wrong.
Does anyone know what the rules are for when a product in bugzilla is valid, or anywhere I can look (log files, scripts I can run) to find out why my configuration is not working?
