title: XAMPP MySQL won't start error 1217
body: <p>I recently got a virus in my computer, and had to reinstall windows. Luckily I have everything on separate HDDs, so I thought it was just to reformat and start XAMPP again. But apparently it wasn't that easy, I keep getting this error message when I try to start MySQL</p>
