OK I see it. I remember similar issue as conflict with some mod. Please check it - disable other mods leave only vBET and vBA and check does it behaves OK. If yes then find which one have conflict by enabling others one by one and checking functionality.
It is definitively something form outside because it is breaking also your images in message - all have JavaScript included and title "Click here to enlarge" - this is not vBET output. Something is changing it or you changed vBET template.
This is how should look output for collapsed area:
Code:
<div class="smallfont" style="margin-bottom:2px">
<img width="16" height="11" src="http://www.vbenterprisetranslator.com/forum/images/vbet/flags/zh-CN.gif" alt="Original text" border="0"/>
<a href="http://www.vbenterprisetranslator.com/forum/say-hello/1-very-first-hello.html#top" onclick="return toggle_collapse('12747267151171')"><img id="collapseimg_12747267151171" src="http://www.vbenterprisetranslator.com/forum/images/buttons/collapse_tcat_collapsed.gif" alt="" border="0" /></a>
</div>
And this is how it looks on your forum:
Code:
<div style="margin-bottom:2px">
<img style="max-width: 500px; cursor: pointer;" onclick="window.open(this.src)" border="0" alt="Click here to enlarge" src="http://www.nusantaraku.org/forum/images/vbet/flags/ms.gif" alt="Original text" border="0"/>
<a href="http://www.nusantaraku.org/forum/diskusi-agama-malaysia/134563-ustaz-azhar-idrus-%5Bkemusykilan-soal-jawap-agama%5D.html#top" class="collapse" style="position: static; float: none;" id="collapse_cel_12747263716369"><img style="max-width: 500px; cursor: pointer;" onclick="window.open(this.src)" border="0" alt="Click here to enlarge" id="cel_12747263716369_img" src="http://www.nusantaraku.org/forum/images/buttons/collapse_40b_collapsed.png" alt="" border="0"/></a>
</div>
Differences are bold.
