Спасибо, попробую.

Working solution here.

I confirm! Working solution. Do not forget to delete the 3 lines after the upgrade.

For my opinion, 777 for all – it’s bad solution.

Audiofanzine Try set 777 for wp-content/upgrade

I assume that the new version has some problem with the rights that interferes with normal renewal and returns blank screen.

I got the same problem at my WordPress site (Russian). When i placed FS_METHOD at wp-config.php, WP returns “Could not create directory. Installation Failed”. Then i change rights 777 at wp-content/upgrade.
And now WordPress returns “You do not have sufficient permissions to access update-core.php”.

Tnx! It interesting realized =)
