After upgrade to 4.7, can’t access Admin

  • Having same issue reported on other threads.

    What I have done to resolve (but it is NOT resolved):
    – Automatic install
    – Manual install
    – Cleared Varnish cache via WP CLI
    – Optimized/Repaired mySQL db
    – Purged CloudFlare cache
    – Purged CDN cache
    – Changed Keys & SALTs
    – Tried Incognito mode & different browsers
    – Turned of security mod feature supplied by DreamHost/DreamPress
    – Beat my head against the desk

    So far, all I have is a sore forehead.

  • @hightechdad Are you getting an error message? Can you elaborate on “can’t access Admin”?

    Haha, yeah sorry.

    I get to the “No Update required” page (for the DB) with this string in the URL –> “/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2Fupdate-core.php” and it redirects me to my home page.

    So when you try to login to the Dashboard as admin you get redirected to that URL and therefore can’t access the Dashboard?

    @hightechdad – Did you flush memcached? If you don’t know how, just ask support to do it for you. Sometimes it gets extra stupid ??

    I am having the same issue. After updating I get an error message:

    No Update Required
    Your WordPress database is already up-to-date!

    There is a button beneath this text that says “Continue”

    After clicking “Continue” I see my site with the admin tool bar at the top. When I click on any link in the tool bar I get the same message. It is an endless loop.

    I have turned off site caching and also cleared the browser cache and the same thing happens every time I log in. I am on Siteground hosting.

    The address on the error page is:
    https://MYSITE.com/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F

    Correct. It was an endless loop. Login – no database upgrade needed – homepage redirect.

    UPDATE: I redownloaded WP 4.7 (this time it wasn’t called “latest.zip” but rather “WordPress-4.7.zip” and I manually reinstalled (deleted wp-admin & wp-includes and replaced *.php files and uploaded the 2 directories) and I got prompted to upgrade my DB. After that, I WAS able to access the Admin page.

    So perhaps there was a file difference between the two zipped files? Or something was updated? Unsure.

    Any ideas? Regardless, it’s working now (not banging my head).

    Thx!

    I just flushed Memcache on my Siteground server and after a couple of page refreshes I finally got into the Dashboard. There were the following warnings at the top:

    Warning: fread() expects parameter 1 to be resource, boolean given in /home/MYSITE/public_html/wp-includes/functions.php on line 4740

    Warning: fclose() expects parameter 1 to be resource, boolean given in /home/MYSITE/public_html/wp-includes/functions.php on line 4743

    Those warnings were related to a plugin. Please ignore. All is working now so the issue must have been the Memcache.

    Thanks

    I have the exact same problem here, and issuing a Memcached flush_all command doesn’t cure it.

    After upgrading to 4.7 the site is still locked in a “No Update Required” loop.

    What a anticlimax!

    Two different sites and in both cases “redis-cli flushall” saved the day.

    @hightechdad

    Was having a similar issue on a dev site on Pantheon, where is was Redis related.

    And now? Did that fix it for you?

    Yep it was fixed by flushing Redis.

    Hello, same problem here, cannot find a solution, anywhere else where to look ?

    Thank you.

    I would check if there is any object caching being used on the site.
