one of our users asked us to change his username.
Let's suppose that the old username is "user_old" and the new username is "user_new".
I changed from ACP (user section) the username of "user_old" to "user_new".
Now if a go to see user's topics in the author section I see again "user_old" instead of "user_new".
If I click on the link of the profile, in the viewprofile window I see "user_new".
The avatar (in viewtopic window) have an <a> link pointing to: "javascript:quotename('user_new,')"
If the user writes new messages they are "authored" as above.
In the database, in the phpbb_users, the field username contains "user_new".
In the database, in the phpbb_post, the field post_username, contains always value "" (empty).
I analized both viewtopic_body.tpl and viewtopic.php and it seems that the username assumes two values, sometimes from $poster and $sometimes from $poster_qq.
It seems that $poster_qq contains the right (new) username.
Thanks for your help!
