WordPress login via JCP shows a critical error

29 Apr, 2026 Jolt Control Panel, Access, WordPress

If you’re using JCP‘s WordPress SSO feature to access the dashboard and see the error message “There has been a critical error on this site”, it usually means the WordPress user that JCP is trying to use has changed.

To clear the issue, trigger a manual refresh of the WordPress installation under the WordPress manager in JCP

Once the refresh has been completed, try using the WordPress login button again.
