problems with theme updating

Hi,
After updating Simplify theme from 4.8 to a new 5.1 version, the home page was broken and I and returned back to version 4.8.

Why did this happen, has something changed? There was no problems with updating the theme before.

My site is http://www.komunikacijaverslui.lt

Thanks for the answer
