We have two environments, one Development and the other Production, where we are using the GPL version of CBSubs. We are a long user of CBSubs, having used the previous versions over the past years.
Both environments are mirrors of each other, although there is always the possibility that we inadvertently got something out of sync between the two.
After closing a development cycle, we find that on the Production side, it is acting as if the Content Protection Plugin isn't installed and active, although we've reconfirmed it is in place and have re-updated it just in case.
On our development side, CBSubs is working properly.
Any suggestions on paths to check while debugging why the Content Protection Plugin might not be active, or moreover, why CBSubs would suddenly stop blocking access to articles and menu items as it is configured to do?
