Laptop shows confused texts?

I urgently need help.

For a few days now, the texts on the website have been completely meaningless and written in the worst German. At first thought it was on a certain page, but this is now on several pages, where such blatant mistakes should definitely not show up. On the cell phone I can call them up normally and the lyrics are quite normal. Does anyone know how to fix this?
