The styling of the theme got messed up

Hello!

The styling of the theme got messed up. This happened for the second time. The was a high load on my website and after that the styling gets messed up. Last time I just reinstalled the child theme and it helped. This time I tried reinstalling the parement and the child theme but it didn’t work. I ruled out everything else with the hosting provider. After poking around and trying do this and that they concluded this must have been the theme. I also think it might, because last time the same thing happed and I fixed it by reinstalling the theme.
Can you you please check what might have gone wrong with the theme.
