kaelabelle on "wordfence alert critical problems"

Thanks for a great plugin that has saved me from tons of problems! I finally have a caching and security solution....I was getting desperate when w3tc broke my page numerous times.

I am getting emails about a critical problem, but I have no idea how to fix it. Here is the message:

Wordfence found the following new issues on "La Chica Paleo".
