blank page when trying to login after update

[sindbad5]

Hi, I've updated an existing 1.54x installation with the files from 1.603. Everthing looks fine but I can not login. If I try, I see a blank page.

Here is my gallery:

There is no errormessage.

You need to run the update script.

Yes! Thank you.

After replacing the 1.5 files with 1.6 files, type  www.your-galleryadress/update.php   and follow the procedure.
