where you quoted this when upgrading from 3.0.5 to 3.0.6:

On a different issue, I noticed that the Warning Points and the Bans that a user has, appeared in postbit,
if the "Who can view Warning Points & Bans" option, was set to all, even if the person viewing was not a register user.
To correct that, open your postbit (or postbit_legacy) template and find:

<if condition="$viewoption=='All'">

Replace that with:

<if condition="$viewoption=='All' and $bbuserinfo[userid]>0">

i don't have that line of code in ostbit or postbit legacy
mind you your hack is the only hack that has altered my postbit and postbit legacy.
