Since latest forum update...

The user name is missing from Posts.

It shows in the Category post lists, (Topic started by  USER NAME) but when you open a post , there is just an empty space

(Written by   ) 

also, the username is not displayed under the user picture!

The username is correctly shown in all replies below  ( by USER NAME ) 

Is there a settings change somewhere?

PM you our site URL...

 PS: No need to PM you - I see the exact same behavior on this site!!  Workaround, please...
