Login ERROR: Cookies are blocked or not supported by your browser.

I spoke to the host and they said that the .htaccess had changed so they fixed it, now the front-end of the site is accessible but I cannot login with my details

I think it’s more like to be a server sessions or cookie issue than a core one. Discuss this login issue with your host as well. Or check the error logs on your server for a more specific error message. If you need help locating them, ask your hosting provider to help you with that.

I have Bluehost as a host, the support is terrible! They are often quite rude and when they come across a problem which they don’t understand (which is surprisingly frequent) they cancel the session!

Could anybody come up with a practical solution for me because I am completely lost?

Did you get chance to check the error logs on your server for a more specific error message.

Bluehost has not provided any info on how to do this – please advise on how I can do this and will provide you with the details, I probably will not be able to understand them.

Try adding this snippet to your theme’s function.php:

//fix for cookie error while login.
setcookie(TEST_COOKIE, 'WP Cookie check', 0, COOKIEPATH, COOKIE_DOMAIN);
if ( SITECOOKIEPATH != COOKIEPATH )
	setcookie(TEST_COOKIE, 'WP Cookie check', 0, SITECOOKIEPATH, COOKIE_DOMAIN);

Hope this helps.

If you google that message you will see quite a few folks that had/have that problem. There does not seem to be a universal cure yet but here is one you might try

@tara I tried this and the code did nothing – thanks for the suggestion though.

@kmessinger The website you linked to suggested renaming the plugins directory, I tried this and I still couldn’t log in unfortunately.

Any other suggestions would be extremely helpful!

@tara – this code worked for me. Thank you SOOOOOOO much!

Hi everyone, solved the problem.
I contacted my host and actually got some good support for once!
He checked the login error and found my theme’s function.php had been corrupted so he reset it to a point before the login error, I logged in successfully, activated theme theme again and now everything is business as usual.

Thanks for your help, I just thought I’d wrap this topic up as I understand that this is a very common problem. I’d say if in doubt, contact your host (depending on their level of customer service) because there are a whole range of potential causes for this error.

Glad to hear that ??

I’ve been having this problem for days and trying everything I could to fix it. I finally found this thread. I reinstated my theme functions from a backup and now it’s all working again! Thanks bradleyagnew for mentioning the corrupt functions.php file!
