Apps settings - Plugixa Exam
A grid of capabilities with a switch on each. Use it to hand somebody a smaller product than the one you installed.

Off means blocked
Switching a capability off does not merely remove its menu item. Its endpoints stop answering, its shortcodes stop registering and its blocks disappear from the inserter.
That is the difference between tidying an interface and actually reducing what the plugin does. A hidden menu item with a live endpoint behind it is not a restriction.
What can be switched off
The grid separates core features that the plugin cannot run without - and which therefore read “always on” - from everything else. A site that only runs untimed practice quizzes can switch off certificates, invigilation, cohorts, webhooks and the rest, and never see them again.
Two things to know first
Nothing is deleted. Turning a capability off stops it being used, not stored. Turn it back on and its screens return with the data intact.
A question type is not the same as its editor. Switching off Images removes the upload button; it does not stop existing picture questions from rendering or being marked.
That distinction was a bug once: switching Images off also disabled the picture question types, so papers containing them would have scored zero with no warning. It is now the documented behaviour, and the principle behind it is worth stating plainly - a capability switch must never silently zero a paper.
Capabilities that fail closed
Switching off Cohorts does not open the exams that depend on it. An exam set to Restricted access denies everyone except administrators when nothing can read its list, because an exam whose restriction cannot be evaluated must not become an open exam.
Troubleshooting
| Symptom | Usual cause |
|---|---|
| A menu item vanished | Its capability is off. |
| A shortcode prints as raw text | Same cause. An off capability does not register its shortcode. |
| A block is missing from the inserter | Same cause. |
| A REST route 404s | Same cause, and this is the intended behaviour. |
| Restricted exams stopped admitting anybody | Cohorts is off. That fails closed on purpose. |
What to do next
- Number and colour settings: General settings.
- Front-end page mapping: Pages settings.
- Per-person restrictions instead of per-site: Roles and Permissions.
