Removed PHP version warning. WordPress is getting stricter with the PHP version it supports. As a result, we no longer feel the need to warn users for too old PHP versions in our software.
Addressed terminology issues. We are now using the term "blocked request" instead of "security exception" to better convey the fact that the detected issue was successfully blocked. Moreover, we are now using the appropriate WordPress terminology "roles" instead of "user groups" for clarity of what some of the options in our software actually do.
Bug fixes and minor improvements.
