Content update breaks site

Hi, whenever there is some activity on my site, such as new comment posted or a page/post being published, my site breaks.

More specifically, the home page becomes an index of links that do not work – rather than being styled and set out correctly.

Clearing the cache resolves the issue, but obviously this is not always practical.

How can I fix this?
