Portfolio not showing

Hi,

on one of my websites, the Portfolio layouts are only loaded, when I am logged in.

For a non-loggged in user, the rotating (v) Logo will display and nothing else.

The console shows the following errors:

plugin-isotope.min.js:1 
Failed to load resource: the server responded with a status of 404 ()

layout-tiles.min.js:1
