# Health Check & Diagnostic Mode

# What is Diagnostic Mode?
When an instance or service is marked as being in Diagnostic Mode, it indicates a problem preventing management through PanelAlpha. This typically occurs when:
- The WordPress instance no longer exists on the hosting server (for example due to direct deletion).
- The hosting account or service associated with the instance does not exist.
Diagnostic Mode activates when PanelAlpha detects issues that prevent successful connection or management during health checks. This status protects your settings and data and alerts you to potential issues.
# Diagnostic Mode in Client Area
Instances or services in Diagnostic Mode still appear in lists, but management options are limited:
- Instance Management — Displays: "Managing the site is currently not possible (Diagnostic Mode). Please contact support for more details."
- Hosting Management — Only the Summary tab is accessible. Other sections display: "Managing the hosting is currently not possible (Diagnostic Mode). Please contact support for more details."
