automatic upgrade does not complete on my installation, I've found the following possible causes here in the forums
- 'wordpress automatic upgrade' plugin was/is not installed
define('WP_TEMP_DIR', ABSPATH . '/wp-content/tmp/');
in the end of my wp-config.php did not resolve the issue
- I set the rights for the temp-folder to 777
The upgrade process still stops with 'Unpacking the core update' but does not give any further debugging information.
Can anyone help? Thanks for spending your time,
