Configure under Settings → Wartungshinweis.
<h3>Usage</h3>
<h3>1. Aktivierung und Zugriff</h3>
Nach der Installation findest du den Menüpunkt unter: 
Einstellungen → Wartungshinweis
Hier kannst du das Verhalten des Plugins vollständig steuern.
<h3>2. Admin-Warnleiste (Dashboard-Hinweis)</h3>
Diese Leiste wird oben im WordPress-Dashboard angezeigt, für alle oder ausgewählte Benutzerrollen.
Einstellungen: 
– Wartung aktiv (Checkbox): Zeigt den Hinweis sofort an, auch außerhalb eines Zeitfensters. 
– Von / Bis (Datum + Uhrzeit): Optionales Zeitfenster, innerhalb dessen der Hinweis automatisch aktiv ist. 
– Nachricht: Freitext oder Vorlage mit Platzhaltern: 
 – <code>{WEEKDAY}</code>, <code>{DATE}</code>, <code>{FROM}</code>, <code>{TO}</code>, <code>{TZ}</code> 
 – <code>{DATETIME_FROM}</code>, <code>{DATETIME_TO}</code>, <code>{WEEKDAY_TO}</code>, <code>{DATE_TO}</code> 
– Sichtbar für Rollen: Bestimme, welche Rollen die Nachricht sehen (z. B. nur Administratoren oder Redakteure).
💡 Wenn kein Text eingegeben ist, erzeugt das Plugin automatisch eine Standardmeldung auf Basis des Zeitfensters.
<h3>3. Frontend-Wartungsmodus</h3>
Wenn aktiviert, ersetzt das Plugin deine öffentliche Website während der Wartungszeit durch eine Maintenance Landingpage.
Einstellungen: 
– Frontend Maintenance aktiv: Schaltet den Modus ein. 
– Bypass für eingeloggte Nutzer: erlaubt angemeldeten Benutzern, die Seite weiterhin normal zu sehen. 
– Landingpage-Modus: 
 1. WordPress-Seite: Nutzt den Inhalt einer bestehenden Seite (Dropdown-Auswahl). 
 2. Custom HTML: Du kannst eine eigene HTML-Struktur direkt im Textfeld hinterlegen. 
 3. Template-Datei: Wähle eine HTML-Datei aus dem Plugin-Verzeichnis (<code>assets/maintenance/templates/</code>).
💡 Das Standard-Template <code>default.html</code> zeigt Titel, Nachricht und Zeitraum automatisch an.
<h3>4. Templates anpassen</h3>
Eigene Templates kannst du einfach ergänzen:
<ol>
<li>Erstelle im Verzeichnis <code>/assets/maintenance/templates/</code> eine Datei, z. B. <code>blue-theme.html</code>.</li>
<li>Verwende Platzhalter für dynamische Inhalte:
<ul>
<li><code>{{TITLE}}</code>, <code>{{MESSAGE}}</code>, <code>{{SITE_NAME}}</code>, <code>{{WINDOW}}</code></li>
<li><code>{{FROM}}</code>, <code>{{TO}}</code>, <code>{{DATE}}</code>, <code>{{DATE_TO}}</code>, <code>{{TZ}}</code></li>
</ul>
</li>
<li>Füge eigene CSS-Dateien unter <code>/assets/maintenance/css/</code> hinzu und binde sie im Template mit <code><link></code> ein.</li>
</ol>
<h3>5. Verhalten und Priorität</h3>
Das Plugin aktiviert die Frontend-Wartung, wenn: 
– „Frontend Maintenance aktiv“ oder 
– ein gültiges Von/Bis-Zeitfenster aktiv ist.
Während dieser Zeit: 
– wird HTTP 503 (Service Unavailable) gesendet, 
– ein <code>Retry-After</code> Header gesetzt, 
– und <code>noindex, nofollow</code> Meta-Tags ausgegeben (SEO-freundlich).
Nach Ablauf oder Deaktivierung wird die normale Seite automatisch wieder angezeigt.
<h3>6. Deinstallation</h3>
Beim Entfernen über „Plugins → Deinstallieren“: 
– werden alle Optionen (<code>ammsg_options</code>, alte <code>ck_admin_maintenance_opts</code>) gelöscht, 
– in Multisite-Umgebungen automatisch für alle Sites bereinigt.
<h3>7. Tipps & Best Practices</h3>
<ul>
<li>Verwende UTC+X Zeitzonen bewusst – die Pluginzeiten richten sich nach der WordPress-Zeitzone.</li>
<li>Wenn du Templates bearbeitest, achte auf UTF-8 ohne BOM.</li>
<li>Du kannst über Filter eigene Verhalten ergänzen:
<ul>
<li><code>ammsg_uninstall_option_keys</code> – eigene Optionen löschen</li>
<li><code>ammsg_frontend_template_replacements</code> – Platzhalter erweitern</li>
</ul>
</li>
</ul>
