[Plugin: W3 Total Cache] New page isn't working with W3 Total Cache

I made my mind for W3 Total Cache three weeks ago. Since installed, my sites performances got really better. However, yesterday I created and published a new page (http://vidaoutdoor.com/sitemamp/) which is not loading. On the contrary, it triggers a server error. But when I deactivate W3 total cache, the page loads normally…

Is there any setting issue I am missing or is it a plugin’s bug?
