Can’t access Dashboard after update to WP 4.7

After running the update to 4.7, I can no longer access my Dashboard. I’ve purged my site cache and browser cache and reloaded the page. When I load the page, it appears that I’m logged in, but when I click the Dashboard (or Edit Page or Updates) button, I get a screen that says “No Update Required. Your WordPress database is already up-to-date!”.

When I click the Continue button on that page, it takes me back to my site’s main page. Vicious loop. This means I can’t deactivate/upadate plugins or themes to check for incompatibility, or to do the manual re-install.

Thankfully, the site itself (scrivenerclasses.com) appears to be working, but I can’t make any changes, and I’m in the middle of trying to build a new class. Thanks.

Same here, I’ve tried all those suggestions and still seeing a 500 error.

gwenhernandez-
do you have access to your files via FTP or your webhosting file manager, if yes, then you can get to your plugin folder.

Lisa: I can. Is there a way to disable plugins from there so I don’t have to delete (or move) the files?

Do you use *ANY* form of caching system? I do mean any form whatsoever, including CloudFlare.

If so, log into that system, and clear the cache. You’re probably seeing a cached version of your site, and it’s looping because it keeps bringing you back to the same cached screen over and over.

You *must* clear caches when doing major updates. And that means all caches, everywhere.

Samuel: I had cleared all the cache locations that I was aware of, but after digging a bit deeper on my host cPanel, I found several more types of cache that needed to be cleared. Will remember that for next time. So, feeling red in the face, but glad to be back up and running. Thanks!!!

Glad you found it. It’s always in the last place you look, because that’s where you fixed it. 🙂

Which kind of cache was it, specifically? Might help us tell others where to look.

LOL, right? 😉

My host is SiteGround and they have their own cache system called SuperCacher, but I’m pretty sure it’s similar to other hosts. It had three parts: Static Cache, Dynamic Cache, and Memcached. I flushed them all and that fixed my issue. Not sure which of the three did the trick or if all were needed. I wasn’t thinking scientifically at the time. 😉

For other Siteground users, SuperCacher is located on the cPanel under the Site Improvement Tools section.

Just FYI to others, I also started getting the http error 500 whenever trying to log back into the dashboard immediately after upgrading from 4.6 to 4.7. I use bluehost, and their technical support was able to just roll back my site to 4.6, so that was my fix for now. Just going to wait it out until they hopefully figure out whatever the bug is.

I am having the same issue, no caching system that I am aware of.

@greenpeas,

If you noticed this a “resolved” topic!

If the troubleshooting already posted made no difference for you, then, as per the Forum Welcome, please post your own topic. That way you stand a good chance of getting full attention to your specific issue. Despite any similarity in symptoms, your issue is likely to be completely different because of possible differences in physical servers, accounts, hosts, plugins, theme, configurations, etc. Thus one problem, on one setup is not indicative of the functionality and reliability of an application as a whole.
