Run the scan
- Open Diagnostic in the WordPress admin menu.
- Click Lancer le diagnostic gratuit (run the free scan).
- Keep the page open while the bar goes through the four groups.
It usually takes under a minute. The scan only reads: it changes no setting, file or content.
The score
The score is out of 100. Each check has a weight: a check that passes earns all of it, a warning earns half, and a critical problem earns nothing. The score is the share earned, so the heaviest checks move it most.
| Score | Grade | Label |
|---|---|---|
| 90 to 100 | A | Bonne santé (good health) |
| 80 to 89 | B | Bonne santé |
| 75 to 79 | B | À améliorer (needs work) |
| 60 to 74 | C | À améliorer |
| 55 to 59 | D | À améliorer |
| 40 to 54 | D | Situation à risque (at risk) |
| 0 to 39 | E | Situation à risque |
From the second scan on, the page also shows how many points the score gained or lost since the last one.
The status of each check
| Status | Meaning |
|---|---|
| Critique (critical) | A real risk to the site or the business. Start here. |
| À améliorer (warning) | Not urgent, but worth fixing. |
| Conforme (passed) | Nothing to do. |
| Non vérifié (not checked) | The check could not run on this server. It is left out of the score. |
Read a problem
Click a problem to open it. Three parts:
- Ce que nous avons constaté (what we found): what the scan saw, with the names of the files, plugins or settings involved.
- Pourquoi c'est important (why it matters): the consequence for the business, in plain language.
- Solution recommandée (recommended fix): what the fix involves, and whether it is a quick fix, a standard job or an advanced one.
The buttons above the list show one group at a time. Checks that passed, and checks that could not run, are folded into two sections at the bottom of the page.
Keep a copy
