There is no way we can access the configuration of wp security ninja, we installed a free version to test, we already saw how botched the test was, but once we bought the pro version, we uninstalled the security ninja module, we reinstalled it and oh surprise, it doesn't leave or ask again for the credentials to configure the $300 pro version that we bought, the first one in the world, is this security software? this is serious? The first thing it generates is frustration, the next is unnecessary and unjustifiable loss of time, the third disappointment and the fourth I N SECURITY. Security software cannot fail to be installed, nor should its user interface be indecipherable gibberish, the difficulty of Use and lack of usability also implies insecurity.

From first disappointments, let's see how long it takes to give us a solution, or if they start to make us dizzy by blaming mainwp and so on, I can see it coming.
