Looking at the logs I can see that when I try to browse to any page behind wp-admin I get a 302 redirect response, and am redirected to
GET /wordpress/wp-admin/upgrade.php?_wp_http_referer=%2Fwordpress%2Fwp-admin%2F HTTP/1.1″ 500
So I’m getting a 500 server error for whatever reason as a result of trying this upgrade.
Browsing other forums I saw it mentioned that one should delete the .maintenance file after a failed upgrade. But I can’t see any such file.
Apologies for jumping on your thread but it sounds like I’m having the very same problem and I’m wondering what to do from here…
