The Éclair settings come preset for a fast, search-friendly site: you only adjust what you need. This reference describes each field with its exact label and its effect on the site, tab by tab. Settings, Users and Security are reserved for administrators: an editor doesn't see them in the menu.
How are the Éclair settings organized?
The Settings menu groups the Éclair settings into 8 tabs. Each tab is saved with the Save button at the bottom of the page; the site cache is then cleared and the message “Settings saved. The site is already up to date ⚡” confirms it.

My profile
My profile gathers the Éclair settings that belong to each person, administrator or editor: author identity, language, password and two-factor authentication. You open it by clicking your name at the bottom of the menu.
Field
Effect
Display name, Login email

Job title / expertise, Bio, Photo, Your online profiles (one link per line)

Log out my other devices
Closes all your other sessions.
Users
Invite someone: Name, Email and Role (Editor or Administrator), then Create account. A temporary password is generated: pass it on in person or through a secure channel. It must be replaced at first login.
Account page: Name, Email, Role, then Reset password, Disable 2FA (lost phone) and Delete account; the account's content stays online.
Roles: the administrator manages everything. The editor manages content, media, categories, menus, messages and redirects.
Security
Protection level: a percentage calculated from 7 points (HTTPS enforced, site address verified, two-factor authentication for every administrator, custom admin URL, supported PHP version, Argon2id passwords, HSTS). The Verify the site address button appears as long as the address isn't verified.
Folder protection test: your browser tries to open internal files, which must stay inaccessible.
File integrity: Scan now lists modified, missing, unknown and suspicious files.
Backup: Download a backup creates a ZIP of data/ and media/; your password is asked for again if you logged in more than 15 minutes ago.
Sessions and blocks: Unblock a blocked address, Log everyone out except you.
Security log: logins, failures, 2FA codes, changed settings, backups, accounts created or deleted.
Recent technical errors: shown only after an error, with the Rebuild the index and clear the cache button.
Menus
Two menus: Main menu (header) and Footer menu.
+ Add a page, a post, a category… suggests your pages, posts, products and categories, the blog and the shop; Custom link adds any URL you like.
Label (optional) replaces the displayed title. Use Move up, Move down, Remove or drag and drop, then Save menus.
Redirects
Old URL, New URL and Type: 301 (permanent, recommended) or 302 (temporary), then Add.
For each redirect, the table shows From, To, the Type (with an auto badge for the ones Éclair created) and the Hits.
Changing the URL of published content creates a 301 automatically. When you delete content, Éclair suggests a URL to redirect the old one to.
Categories
It contains: Posts (blog) or Products (shop), a choice offered when you create the category while the shop is open.
Name, Slug (URL) (automatic if empty), Description (2 to 4 sentences shown at the top of the category page) and SEO title (optional).
Each category is a pillar page, at /blog/my-category or /shop/my-category. Deleting a category leaves its posts published, without a category.
The Categories menu entry only appears if the blog is turned on.
Frequently asked questions about settings
Can an editor change the Éclair settings?
No. Settings, Users and Security are reserved for administrators; an editor takes care of content and everything around it: media, categories, menus, messages and redirects.
Why does Éclair ask for my password again?
For sensitive actions (Advanced tab, backup, account management, email change) when you logged in more than 15 minutes ago. If someone uses a session you left open, they can't go any further.
Where do I change the admin language?
In My profile › Admin language: each person chooses their own from 7 languages. The public site's language is set in Settings › General, and the language of each piece of content in the editor (multilingual site).
To go further, the official Éclair guide describes these same Éclair settings throughout its sections, and the files reference shows where each one is stored.
