I think I got the error.
There is one little thing wrong in the original install readme of the Avatar hack(when you install it on 1.1.4). It says the following should be changed:
$userinfo=$DB_site->query_first("SELECT userid,email,username,usertitle,signature,showemai l,homepage,icq,aim,yahoo,joindate,posts FROM user WHERE userid=$userid");
In the showthread.php file. But it can't be found in this file. You had to change something in an other php file. But I forgot in which file, and since the Avatar post is deleted it pretty hard to find out.
I think this is causing the Avatars not showing up in posts.
Anyone know which file had to be changed instead of the showthread file for the 1.1.4 version?
Please help, because the Avatar hack rules
Shims.
