@scaturan:
I don’t know why it suddenly become to “normal”.
My host is virtual host! So I can restore to some point before. Then I restore to 4.5.3. Then manually update to 4.6.1. At this time, the /wp-admin/index.php still “normal”. But when I restored the database, the page renders blank.
So i think the problem at the database. Then I twice restore to 4.5.3! When I restored to 4.5.3 I have remembered I had done not backup one article yet. So I restore to 4.6.1 using virtual tools. When this time, I can not access my page. Show me “can’t establish to database”. Then I restart the Mysqld. Then the /wp-admin/index.php page is OK!
I don’t why! just wish this can help to you!
@scaturan I have the same problem! Like you do the things, I removed the wp_dashboard_setup() from /wp-admin/index.php file. Then I can see the page, but no dashboard 🙁
My version of 4.6.1
