I've already reported this to Valve. The CS:GO official API is returning empty objects 95% of the times, which is why you're seeing this error message.

Other sites rely on the private Steam Community API but it isn't really meant for third-party use, so I stuck with the official API because I figured that would be more sensible. Turns out it has more issues, so I kind of shot myself in the leg.

• Fixed the stuck notifications issue
  
• Sidebar no longer scrolls out, but displays tooltips on what each icon is.
  
• Lightened text across the site by 10%
