all it is is airsound's avatar being http rather than https
Oooer how embarrassing - a public naming and shaming. So here's a public apology. I'm very sorry for being the cause of consternation and disruption amongst the estimable PPRuNerhood.
It was a complete surprise to me, especially since the avatar, for which I had to pay, has been there for years. Anyway, I think it's being fixed. I hope so.
Sorry again
airsound
