ok now I noticed a new issue ,
I put a conditional command for the threadbit template edit, I mean I edited the threadbit template like this:
HTML Code:
<if condition="$show['guest']">
<td class="alt1" id="td_threadtitle_$thread[realthreadid]" title="$thread[preview]">
<else />
<td class="alt1 jqt_threadbit_tooltip_trigger" id="td_threadtitle_$thread[realthreadid]" title="<table class="threadbit_tooltip">
<tr>
<td class="avatar_blok">
<img src="$thread[avatarurl]" border="0"style="max-width:80px;min-width:60px; max-height:90px;" />
</td>
<td class="user_detail">
<p class="borderbottom"><i>Preview</i></p>
<p class="details2">$thread[preview]</p>
<h5>Started by: $thread[postusername], $thread[lastpostdate] $thread[lastposttime]</h5>
</td>
</tr>
</table>">
</if>
now when I visit the threads .. (with having the hack enabled and obviously when I am logged in) , thread pages are blank ...
so I disabled the hack temporary ...
