Lay Theme Forum

I guess it depends on if you are logged in to chrome with an account. Logged out nothing works, these errors are in the console:

When logged in, all links and thumbnails work and the console looks like this:

A majority of our website users cannot click on links: neither thumbnais, nor normal links.
Our website is anteup.at.
If you right-click on "Open link in new tab" everything works normally. We have disabled all plugins and removed CSS & JS and it still doesn't work. We have the latest version of Lay Theme and the cache is cleared. It doesn't matter which browser is used: my colleague and I both use the latest google chrome version. Everything works normally for me, but not for my colleague.

What else can we do?
