There is really something weird going on. I update the site and the homepage is not functioning ok. The other page does. If i’m logged in on my wp and I look at the home page the page is ok. If I logged out the home page is not. Also in different browsers the page is not ok. Can you figure it out?
I already find out what went wrong. It is the caching plugin I use. After pdating something went wrong. I deactivate the plugin ( when I activate it again it gives the same error) It is the W3 Total Cache plugin.
