I can’t offer a solution. But I have 2 websites with same issue – one is no longer viewable after WordPress 4.6 “Pepper”. I got peppered all right.
I updated through WordPress interface. Haven’t had this issue in years. But not very happy right now.
Webhost is A Small Orange. One site is run on VPS other is just regular hosting.
VPS site returns this error.
Forbidden
You don’t have permission to access /wordpress/wp-admin/index.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
Other website just offers a blank page.
Never seen the above error with previous updates.
Can’t edit comment above = strike 1 up 1 down. Both websites offline. Although only VPS showing the 403 error. Obviously I was getting cached version in browser for site I thought was still live.
Everything worked smooth until update = so I’d assume there is something there causing end user issues.
Again can’t edit above – so having to add yet another reply.
It would seem my choice of theme Alexis which I have used for years and loved the look – is what broke websites.
Now I have a crappy looking website that works. Have no time or want to play with child themes tweaking code etc.
Hello, I have a similar issue. After updating my development machine from the previous version to 4.6, I got redirected to
/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F
Where the message is “Your WordPress database is already up to date”
[Continue]
Any attempt to use /wp-admin/ redirects me to this page.
I tried renaming the plug-ins and themes directory to “old-<name>”, but it didn’t help.
Also tried to clear caches, cookies etc…
I found my problem. In my case, the old DB version (db_upgraded) stored in the options table was in Memcached. I had to flush memcached, and I can login again now.
I noticed this by tracing the PHP code in /wp-admin/admin.php.
Good luck,
Hubert, it looks after upgrading I ran into the same situation. I’m getting the same url /wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F
I think your solution will work, BUT I don’t know how to
“I had to flush memcached, and I can login again now.
I noticed this by tracing the PHP code in /wp-admin/admin.php.”
Would you mind letting me how you did that?
Nevermind. W3 Total Cache was the culprit. After deleting the advanced-cache.php, db.php, and object-cache.php I was able to login to the dashboard.
