Plugin Abandoned?

My company uses this plugin across multiple websites and we love it! However, it constantly generates warnings from security plugins like WordFence because it hasn’t been updated in 7 years. WordFence has flagged it as “Plugin Abandoned” which doesn’t provide much confidence in our clients. It also generates PHP errors because $_SERVER[‘HTTP_REFERER’] is sometimes undefined (around line 76).

Would you consider allowing us to take over maintenance of the plugin so that we can bring the code up-to-date and fix the PHP error?

Thanks!
