Drupal: update.php error -

I am copying my Drupal installation to another folder and I copied the related database.

When I run update.php on the new copy, I get the following error:

Should I disable some modules .. or Is there something about Doppel Corps?

(I'm using Version 6.16)

I've flushed all the cache and the website is offline.

Thanks

You must log in to run update.php .. In fact, I'm also wondering how you can run update.php without logging in as an administrator. O_O

  list ($ module, $ version) = array_pop (Reset ($ _ session ['update' removal ']) See error reported in error ...);  

You can see the use of the $ _ session / array;

If you are not logged in, then you probably do not have a php session ...
