Wordfence Blocking all Javascript actions

This is wierd and so hard to let you know how is actually happening.

Basically when having the plugin activated and the user is logged in, it blocks the JavaScript in the frontend and nothing is working anymore, even in Learning Mode it doesn’t work and I got to deactivate it. Any idea where I should take a look?, because I cannot use the plugin.

I could not find any error or something that is telling me why. It happened for me on several sites already.
