Change forum path?

I digged into the code and found that it actually checks in the vb database for the correct values. I did some trouble shooting and came up with the fact that it doesn't seem to unserialize the data field. So I found (on php.net) a function for checking if a string is unserializeable and according to that test the string fails on this part:

   $str = 's';
   $array = 'a';
   $integer = 'i';
   $any = '[^}]*?';
   $count = '\d+';
   $content = '"(?:\\\";|.)*?";';
   $open_tag = '\{';
   $close_tag = '\}';
   $parameter = "($str|$array|$integer|$any):($count)" . "(?:[:]($open_tag|$content)|[;])";
   $preg = "/$parameter|($close_tag)/";
   if( !preg_match_all( $preg, $string, $matches ) )
   {
       $errmsg = 'not a serialized string';
       return false;
   }

Is anyone else having this problem? I have tried to copy the options data field once again from the original database but without luck.

I figured I was wrong when I said the string fails the test. Although I can't even unserialize the simpliest string:

a:1:{s:16:"errorlogsecurity";}

var_dump(unserialize($data->data));

if($options = unserialize($data->data))
echo " OK";
else
echo " ERROR";

Outputs: bool(false) ERROR

I'm out of ideas at the moment.

I realized that my test string wasn't properly serialized and in the same time I can say I'm not familiar with serialization but I'm starting to understand it :)

So I tried this string instead: a:1:{s:5:"Hello";s:5:"World";}
and I may unserialize it. Although I still cannot unserialize the options row from the vbulletin database. How can I verify the string to figure out why PHP can't unserialize it? Isn't it kind of strange that my vBulletin forum is able to (un)serialize it?

Thanks TheOverclocked,
Still can't get it to work though. I'm trying to unserialize the row where title = options in the datastore table in the vB database.
The code is more or less from the original drupalvb (drupalvb.inc.php):

 $result = db_query(_drupalvb_prefix("SELECT data FROM {datastore} WHERE title = 'options'"));
  $data = db_fetch_object($result);

    var_dump(unserialize($data->data));

    if($options = unserialize($data->data))
        echo " OK";
    else
        echo " ERROR";

This prints "ERROR".
I just want the module to work ;)
