“Security is not fully operational”
For Fullworks Security to provide protection it runs code even before WordPress is loaded. To enable this requires a configuration file setting.
If the configuration file can not be written too, then the pre WordPress features will not be enabled.
In many cases, you can try deactivating the plugin and reactivating. If you still get the message that it is not fully operational, please send us a support ticket so we can advise the appropriate course of action.
