OK fixed it.
I don't undertand why but remove all spaces in template forumhome_loggedinuser fixed it.
FROM:
Code:
<if condition="$loggedin[userid]">
<a href="member.php?$session[sessionurl]u=$loggedin[userid]">$loggedin[musername]</a>$loggedin[invisiblemark]$loggedin[buddymark]
<else />
$loggedin[musername]
</if>
TO:
Code:
<if condition="$loggedin[userid]"><a href="member.php?$session[sessionurl]u=$loggedin[userid]">$loggedin[musername]</a>$loggedin[invisiblemark]$loggedin[buddymark]<else />$loggedin[musername]</if>
Now, it's fine.
Thanks amykhar
