"Cookies are blocked or not supported by your browser."

when users attempt to login to WP site, they receive an error message:

“Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.”

Cookies are enabled. Site was running well until last weekend. Never had the message before, site is unchanged since 3.7, and with cookies enabled in all browsers, you still see the message when logging in.

We disabled themes and plugins, to no avail.
Tried the other hacks in several threads, but no cigar. All they did was produce a white screen.

Any one else experiencing this or have a suggested solution? All help is appreciated. I need to update my site, but I can’t login to the admin screen!

The only solution that worked and let me into the admin area is
```
function wp_validate_auth_cookie($cookie='',$scheme='') {
    return 1; // admin user id
}
```
but this opens the site wide open to all visitors being admins (which is OK to update or upgrade something really quick….

The issue seems to be different from host to host and something within the core changed that results in this error… but what? It’s all either about cookies or php…

I think it’s more like to be a server sessions or cookie issue than a core one. Have you spoken to your hosts about it. Or checked your error logs?

@amsgator thanks for that. non-www to www redirection is the first thing I did. Still no go.

Disabling the test cookie check also did not work. Cookie is just not being set at all…

Trying to install another instance of WP on the same server now to see if it works.

Clear your cookies and cache. If you have the cookie still in the browser and you block the check it will freak out.

I hade this ccokis problem i 2 weeks with brand new installation, I got my own tread and nobody answered me there. I am not that technical and it should not be like that – whrite som other skripts. And I cleared cookies an cash, cheked on other browsers and other computers – didnt work easer!

It is Word Press problem with 3.7.1!

Thanks to amsgator I inastalled 3.7 and its works! So it can not be host problem.

I just wonder if some place I should swich off automatic uoodate? Or wp will ask me before uppgrade?

I was having the same issue all last week, applied some of these fixes, then it worked for a while, then I got the white screen of death. I needed to revamp my site anyway so I blew it away and rebuilt it. Then lo and behold it happened again today. I was on Cloudflare but reverted back to my default name servers before trying to troubleshoot. And now the problem has gone away. Hmmmm…Now I’m not sure what to do, will it happen again?

Follow up, just checked from another machine and the problem is still present!

This is a bit random chaps, but I’ve been following these threads on this issue for weeks as I too have this problem on my main site.

I don’t run varnish on my system and all plugins are so very much tried and tested that I didn’t think it could be them.

The thing that seemed to fix this issue on my 2 sites was to deactivate and then reactivate Akismet.

I have absolutely NO idea whatsoever if Akismet could or would play a part with authentication for login in any way, but disabling and enabling the plugin has flushed something out of the system that was causing this problem.

If you find yourself with this issue, I would recommend you deactivating all plugins and then re-enabling them ONE AT A TIME.

Not sure what happens in that re-activating phase, but it sorted my problem out with this cookies issue.

All now works great again after weeks of thinking it was a core WP issue.

Hope that helps.

My cookie problem seems to be related to cloudflare like @clodius!

I have had pagerules on: site.com/* to be totally cached while site.com/wp-admin set to bypass caching completely.

Now i will do a third pagerule for wp-login.php not to cache anything, hope this helps!

I’ve now got the same problem on some of my blogs.

When I try to log in to my Control Panel I get the message “ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.”

I’ve gone through the instructions for clearing cookies on http://support.mozilla.org/en-US/kb/websites-say-cookies-are-blocked-unblock-them with no success.

I’ve tried a different browser too, but the problem persists.

I use CloudFlare, and I’ve never had a problem before with logging in to my WP panel, but just in case I’ve added a Pagerule to bypass caching of wp-admin and wp-login.php but still I can’t log in.

I upgraded to the latest WP version a few days ago, but I have been able to login ok since then, so I assume it isn’t this latest version that’s causing the issues.

Apologies, I’m one of the offenders in this.

I have removed some Cloudflare pagerules so now my Admin login is not cached, and everything is back to normal.

I know I’m breaking the law by replying to this thread but it is pertinent to what a member has posted.

With regards to my issue it did resurface again today. This is after the 3.8 update too.

@rossagrant…Bullseye. I FTP to my plugins dir, renamed Akismet to Akismetxx, and boom, I got into the admin area. Big thanks to you!

I’m replying only to post a workaround for this same problem I’ve had. The problem only shows up on one site of several – even though all are configured identically. When I try to login to the problem site, it clears the user name and password fields, and give me the “Cookies are not supported…” message. I leave the user name and password fields blank and hit reload. Firefox asks me if I want to resend data (Yes), and I’m whisked away to the admin area. Not a proper fix, but it beats a poke in the ribs.
Meanwhile, the search for a ‘real’ solution goes on.

Hi guys!

I’ve gotten to the bottom of this for sure now.

Some themes that have the sidebar login widget developed before the latest WP update of 3.7 will more than likely have a line of code which states:

<input type="hidden" name="testcookie" value="1" />

Particularly if you use Buddypress.

See this trac ticket here.

http://buddypress.trac.wordpress.org/changeset/7485

If you are using BP, you simply need to delete that line from your sidebar.php or BuddyPress navigation file containing that line of code.

100% fixed all of my issues.
