Forum Google search result not showing Meta Description after upgrade
 

Hi,

a few days ago I upgraded from 3.8.6 to 4.0.7 (and yes, I am happy I finally took that step ;-)). There is among a few other small issues one I cannot solve so far: when you search for my forum the result doesn't show the Meta Description as it used to do on 3.8.6. Instead it is showing content of a thread (no idea why exactly this very thread). It doesn't matter which key words you search for, it's always the same. Of course I want the Meta Description to be displayed in the results. Any idea how I can fix this?

Thank you very much!
