btizer – out of curiosity, after you were able to login in did you encounter an error like this one upon going to the Manage Plugins page in admin:

The plugin ../../../../../../../../../../../../../../../../../../../../tmp/tmpiNR1gx/sess_7b0e28c049ba9da373a1e901574c02a8 has been deactivated due to an error: Invalid plugin.

bitzer – I think that many people owe you many thanks. I was just able to fix a blog that’s been having this problem for weeks now. My hunch is that all of you have the same plugin installed that was interfering with logging in to update the WP database. By renaming the plugin directory, you effectively disabled that plugin, stopping the interference and allowing you to get to the DB update page.

Hurray!
