Once Plugin was activated couldn't access backend

I thought this plugin would be cool however never had the chance of using it. The moment I activated the plugin it didn’t allow me to access my backend of my site anymore.

I tried everything from clearing cache and reading hordes of comments on backend issues. It wasn’t until I logged into my hosting account and disabled the plugin that I was able to access my backend again.

Perhaps I’m a newbie when it comes to these things and did something wrong, but from a newbie’s perspective…this plugin was worthless to me. I’ll be looking for other landing page plugins.
