Opening start page, news items seem to stop intermittently on the 3rd item and console has an exception "error while executing javascript action expression" and only part of the news item displays. The css box does not display correctly and the top of the css box for the 4th news item does not display. If I move up and down slider, it becomes ok.

The times it does display correctly, there is still the same error on console.

I tried deleting the news items that seemed to get their css display stuffed up, but the problem persists.
