usernames in qoutes for member/guests

[ReBe]

Hi all,

i have make the usernames in quotes invisible vor guests. Members can see the names. I edit the template bbcode_quotes per TMS:

I replace

<img src="{vb:stylevar imgdir_misc}/quote_icon.png" alt="{vb:rawphrase quote}" /> {vb:rawphrase originally_posted_by_x, {vb:raw username}}

with

<img src="{vb:stylevar imgdir_misc}/quote_icon.png" alt="{vb:rawphrase quote}" /> 
<vb:if condition="$show['member']">{vb:rawphrase originally_posted_by_x, {vb:raw username}}
<vb:else />
<span style="font-weight:bold; font-size:10pt">{vb:rawphrase quote}</span>
</vb:if>

After that, i create new postcache. Now it works fine. But after some hours can members in some postings not seeing the names and guest see the names in some posts. If i now let the postcache create new, then the errors are gone.

I think if a guest look as the first user to a post, then the posting comes with no username in quote in the postcache. And if the a member looks to this posting, it comes from the postcache. And thats why the member not see the username. I hope you can follow me.

How can i fix it? We have realnames in our foum, so ist necassery to hide the usernames for guest/searchengines.
