I think some problem in this code,because since 2 days crazy my mind.Some thread not showing,empty pages.

Today disable this extension,after see that thread without any problem..
When I press that link this error occured in İnternet Explorer.

Internet Explorer was unable to link to the Web page you requested. The page might be temporarily unavailable.

Any idea for that ?

It seems like there was 1 line missing in the Bitfield XML, which caused the BBCode Setting to not show up.
Here is the corrected File, i've also updated the ZIP

Internet Explorer was unable to link to the Web page you requested. The page might be temporarily unavailable.

I try many times,when this hack is disable problem solve,also report this problem in vbulletin.com but this is not a vb bug.

Here is the sample....now this hack is active...Realy interesting...

I don't understand what you are trying to tell me, sorry.
If somebody else does: Please enlighten me.

This hack active = Some threads not show (white screen)
This hack inactive = Everthing is OK

Is it clear ?

Now that sounds clear :)
But I got no idea what could be causing this, nor do I know how to reproduce it - therefore I most likely won't be able to provide a fix.

I find a problem,but where I dont't know.

Problem is Derefer/Detect External URLs section.When I disable only this one everything is OK,every thread is show up.

Which PHP Version do you use?

4.4.0
