You need to go back and find the error in the logs before that. That is, the one for the very first request against the process, or when WSGI script was loaded if pre-loading has been enabled. The error you give isn't the root cause, but the result of subsequent requests failing after the first and is because Django initialisation is no longer re-entrant when it fails the first time.

I would check the httpd logs.

Or, it seems your Horizon is installed incorrectly. Reinstall it and watch out for warnings.

My Horizon installed correct, and it run perfect, util I restart the httpd failed.
