Info: This feature requires Enterprise Server version 9.1 or higher.
Under very rare circumstances, a mixture of PHP files can exist in Enterprise Server. The most likely scenario of this occurring is during an upgrade of Enterprise Server. As part of the upgrade process therefore, accessing the Health Check page automatically clears the Zend OPcache folder so this scenario should automatically resolve itself.
Should the need arise though, the Zend OPcache can also be cleared manually.
Step 1. In Enterprise Server, click Advanced in the Maintenance menu or on the Home page. A page with all advanced Maintenance features appears.
Step 2. Click Clear Zend OPcache.
The cache of Zend OPcache is cleared.
