Unable to Log In –Cookies Are Blocked Due To Unexpected Output?

I solved my problem.

First I just cleared all white spaces before <?php tag in functions.php

Secondly I didn’t used multiple <?php ?> tags. I’ve just put my entire code on a single <?php tag with no ending ?> so that i can add other functions required later on.

Finally I’ve saved the changes and it worked out!

Hope this works for you too poonam. Best of luck!!!

Thanks in Advanced

Hi Everyone

As not having technical knowledge how to tackle this issue, I would appreciate someone giving me a step by step instructions how to get rid of this “Cookies Are Blocked Due To Unexpected Output”.

I have an access to web ftp and my php admin but I do not know how to proceed really further from there.

Many thanks in advance!

Use FTP, delete “limit login attempts” plugin

You can have a look at this article for your solution :
https://www.bhawanigarg.com/oh-wordpress-login-error/

this turn out to be a plugin bug which i solved by deleting all plugins and re-instralling them one by one until the problem came out again. the only way i could access the wp-admin was to use ftp to re-name the plugin folder for a second and then re-naming it back. thx for the support.

Thanks Saugat I solved my problem with your advice. This is the function.php file where I used closing php tag ?> Once I removed this tag my site works properly again.

Like others, I removed the closing ?> php tag in my functions file and it fixed the problem.

Closing the php ?> tag in my theme’s functions.php file fixed this for me too.

This doesn’t seem great practice, though. If someone finds out what’s causing the problem I’d appreciate it if it was posted here.

Sounds like at least two of you are hosted on really badly configured servers. There is no way that a missing closing ?> at the end of file would cause this problem on a well-configured server.

esmi, based on your certainty I’m assuming you have experience with setting up servers, so could you let us know specifically what part of our servers (or php-config etc.) are badly-configured? This way we can add it to a trac ticket and everyone can benefit.

… it MUST be the function files … same problems like you guys (i cloned a copy wp 3.9 with ducplicator plugin) and couldn’t log in … i change name of the “heavy modified” themes, i used (via ftp) and let wp switch to default theme “twenty fourteen” (!) – THEN i could log in, changed my themes to the original name back (via ftpo) and select the child theme via wp admin …then i also changed my passwort (admin) from within wp-admin and logout … no problems anymore, nor error message, normal loging procedure… hope that helps some of you …

Hey guys!
It finally worked.
I notices someone stated that one of the active plugins produces unexpected output, causing a “headers already sent” warning and consequently preventing WordPress from setting the test cookie.
But I received no message , only “Cookies are blocked…”
Trying to find a plugin (none of other measures worked), that causes such malfunctioning, I found that Justified Image Grid causes that.

Now login works as it should.

Will have to fix that plugin now =)

I do not have the tech knowledge to understand or attempt to do anything you guys did….is there a tech support or customer service thing i can go to? we need to change our site for important details today and we need access, I dont understand what you guys are doing, I cannot access any options on our site to change anything please someone reply at [Moderator note: We do not provide email support here] with an answer

If you have paid people to develop your site for you then you should contact those people. If you have developed your site yourself, and if you’re not considering to hire someone to resolve this for you then these volunteer-based forums are the only support you can rely on; there is no tech team to phone up.

so what is the problem then? why is this suddenly an issue and yes we did this ourselves is there a step by step on what to do to fix this?
